Big, bold, smoky Mexican flavours make this chilli chicken one of the most satisfying dinners in my rotation, and at 40g of protein for around 420 calories it is a proper GLP-1 winner. Chicken cooked in a smoky tomato, pepper and bean sauce delivers a serious protein and fibre hit, and it is endlessly flexible — pile it into wraps, over rice, or into a bowl with all the trimmings.
A quick word first: I am not a doctor or a dietitian, just someone who lived this. None of these foods or supplements are medication, and if you are on a GLP-1, check anything new with your GP or pharmacist. Right, let us get to it.

Why this smoky chilli chicken works
This dish brings together everything a good GLP-1 dinner needs, with a load of flavour on top.
40g of protein and 8g of fibre. The chicken and beans together deliver a big hit of both, which is exactly the combination that keeps you full and your digestion moving.
Huge flavour from smoky spices. Smoked paprika, cumin and chilli give this real depth and warmth, so a lean, healthy dinner tastes anything but boring.
Endlessly flexible. Serve it in wraps, over rice or cauliflower rice, or in a loaded bowl — one recipe, many dinners, which keeps things interesting.
Why flavour is a serious weight-loss tool
People tend to think of bold flavours as an indulgence, but I have come to see them as one of the most useful tools for losing weight. Here is why: a meal that is genuinely delicious and satisfying leaves you content, whereas a bland, joyless one leaves you looking for something more, usually something you should not have. Big, smoky, spicy flavours like the ones in this Mexican chilli chicken deliver a huge amount of satisfaction for very few calories, so you finish the meal feeling like you have properly eaten rather than feeling short-changed.
Spices are the key. They add enormous depth and interest to food for essentially no calories — a teaspoon of smoked paprika or cumin transforms a plain chicken dish into something you crave. On a GLP-1, where you are eating smaller portions, making every one of those portions taste incredible is genuinely important for staying satisfied and on track. Building a well-stocked spice cupboard and learning to use it was one of the best investments I made in my own weight loss. Do not think of bold flavour as a treat to be rationed — think of it as a tool that makes healthy, lower-calorie eating feel generous and satisfying. This dish is a perfect example of flavour doing the heavy lifting.
The macros that matter
Here is roughly what one serving gives you. Treat these as a guide rather than gospel, since it depends on your exact ingredients and portions:
| Approx per serving | Amount |
|---|---|
| Calories | ~420 kcal |
| Protein | 40g |
| Carbohydrate | 24g |
| Fat | 16g |
| Fibre | 8g |
The protein figure is the one I watch on a GLP-1. As a rough guide I aim for somewhere around 1.2 to 1.6g of protein per kilo of body weight across the day to protect muscle while losing fat, and I judge every meal by how much of that it contributes. I log meals like this in Cronometer (it is free) so I know I am actually hitting my targets rather than hoping. The first time I tracked properly I realised I was eating far less protein than I thought, so if you have never done it, give it two weeks.
What you need (serves 1)
- 2 chicken breasts (about 300g), diced
- 1 onion, chopped
- 1 red pepper, sliced
- 2 cloves garlic, crushed
- 1 tsp smoked paprika
- 1 tsp ground cumin
- ½ tsp chilli powder
- 1 tin chopped tomatoes
- 1 tin black beans or kidney beans, drained
- 1 tsp olive oil
- Fresh coriander and a squeeze of lime
- To serve: wraps, rice, or cauliflower rice
How to make it
- Heat the olive oil in a large pan and cook the diced chicken until golden, then set aside.
- Soften the onion and pepper in the same pan for a few minutes.
- Add the garlic and all the spices and cook for a minute until fragrant.
- Add the chopped tomatoes and drained beans, and return the chicken to the pan.
- Simmer for 12–15 minutes until the chicken is cooked through and the sauce has thickened.
- Season, finish with a squeeze of lime and plenty of fresh coriander.
- Serve in wraps, over rice or cauliflower rice, or in a bowl with your favourite toppings.
Adjusting it to your goals
This is high in protein and fibre, and flexible:
Lower the carbs. Serve over cauliflower rice or in lettuce cups instead of wraps or rice.
Make it a loaded bowl. Top with avocado, a little cheese, salsa and Greek yoghurt for a proper burrito bowl.
Add more beans or veg. For even more fibre and volume. See fibre on GLP-1.
Building a spice cupboard that transforms your cooking
If you want to make healthy eating genuinely enjoyable, few things pay off like a well-stocked spice cupboard. Spices add huge flavour for zero calories, and they are what let you turn cheap, lean ingredients into dishes you actively crave. You do not need dozens — a core handful will cover most of what you cook. Smoked paprika brings a deep, smoky warmth that is brilliant in Mexican and Spanish dishes. Cumin adds an earthy, savoury base to curries, chillies and Mexican food. Ground coriander is fresh and citrusy. Chilli powder or flakes bring heat you can dial up or down. Turmeric adds colour and warmth. Add garlic and onion granules, dried oregano and a good curry powder, and you can flavour food from half the cuisines in the world. Buy them in larger, cheaper bags rather than tiny expensive jars, store them somewhere dark, and replace them when they lose their punch. Learning which spices suit which dishes, and getting confident about being generous with them, is one of the single biggest upgrades you can make to your everyday cooking. It is what stops healthy food being boring, and boredom is what ends most diets.
A batch-cook and meal-prep star
This is a brilliant batch-cook. It keeps well for a few days, freezes perfectly, and the flavours deepen over time. Make a big batch and you have the base for wraps, bowls and rice dinners all week, or portions in the freezer for busy nights. The leftovers make a superb next-day high-protein lunch, loaded into a wrap or over a salad. A cornerstone of my meal prep ideas for Mounjaro.
How it fits a full day of eating
At 40g of protein and 8g of fibre, this is one of the most complete dinners in the series, doing a huge amount of the day’s work in one dish. I still aim for a solid high-protein breakfasts and high-protein lunch, but a dinner this strong on both protein and fibre makes hitting my targets easy.
Serve it over cauliflower rice or in lettuce cups if I have had carbs earlier, or with rice for more energy. a protein shake covers any post-workout gap. This is exactly the kind of high-protein, high-fibre dinner that makes eating well effortless — my complete GLP-1 guide explains the framework.
No appetite today?
On a low-appetite evening, a small bowl of this still banks serious protein and fibre, and the smoky spice can help wake up an appetite that has gone missing. Skip the wrap and just have the saucy chicken and beans. When cooking is beyond you, a freezer portion or HelloFresh keeps proper meals coming. More in what to eat with no appetite.
Supplements that pair well
With chicken and beans, this is high in protein and fibre, so a probiotic like Pre + Pro 15 complements the fibre well. I take a daily Super Supplemental for general cover. If you are increasing your fibre with dishes like this, do it gradually — see my constipation on GLP-1 guide. The free Lily & Loaf lifestyle analysis matches a routine to your goals.
Frequently asked questions
Is this a healthy alternative to a takeaway?
Very much so — it delivers all the bold Mexican flavours of a takeaway or fast-food burrito bowl with lean chicken, beans and no excess oil, at 40g of protein for around 420 calories. Far better for you and cheaper too.
How do I make it lower carb?
Serve it over cauliflower rice or in crisp lettuce cups instead of wraps or rice. The protein-and-bean base is the star, so the vehicle is up to you.
Can I make it a vegetarian version?
Yes — leave out the chicken and double the beans, adding a second tin or a mix of black and kidney beans. You keep the fibre and get a solid hit of plant protein.
How spicy is it?
As spicy as you like — the chilli powder is easy to dial up or down. Start mild and add more, or serve with yoghurt or avocado to cool it. The smoky paprika and cumin give flavour without heat.
Does it freeze well?
Brilliantly — it is a great freezer meal and the flavours deepen over time. Make a big batch and portion it for easy dinners, wraps and lunches all week.
The bottom line
Mexican chilli chicken is bold, smoky, satisfying food that happens to be a GLP-1 winner — 40g of protein and 8g of fibre for around 420 calories, endlessly flexible across wraps, bowls and rice. Big flavour is one of the most useful weight-loss tools going, because a satisfying meal keeps you content and on track. Build your spice cupboard and let flavour do the work. To match your supplements to a high-protein, high-fibre routine, the free Lily & Loaf lifestyle analysis is a quick, no-pressure check.
The tools I lean on
If you are putting a GLP-1 routine together, this is the order I would do it in, free tools first:
- Track a fortnight of food in Cronometer so you can see your real protein and calories.
- Take the free Lily & Loaf lifestyle analysis to find the supplements actually worth buying.
- Start an Audible trial for something to listen to while you cook or walk.
- Keep HelloFresh on standby for the weeks cooking from scratch just is not happening.
- Batch-cook and freeze portions in a set of freezer-safe containers so there is always a healthy dinner a few minutes away.
A bit about me
I am Alan Spicer. I lost around seven stone on Mounjaro and filmed the whole thing, warts and all, on my YouTube channel. Simple, protein-first dinners like this were a real part of how I held onto muscle and kept the weight off.
