Sometimes simple is exactly what you want. This beetroot, lettuce, avocado and tomato salad is a fresh, colourful, no-fuss lunch that comes together in minutes and delivers a lovely 8g of fibre for around 260 calories. It is light, it is vibrant, and it is the kind of clean, easy plate I reach for when I want something fresh without any faff at all.
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.
For why fibre matters on the jab, see fibre on GLP-1, and for building a filling salad, my complete GLP-1 guide.
Why simple salads still deserve a place
Not everything has to be a production. A clean, simple salad has real value.
It is genuinely quick and easy. Four main ingredients, a quick dressing, done. On a busy day, simple is what actually gets eaten.
Avocado brings fibre and healthy fats. It is what stops this being just a bowl of leaves — the fats add staying power and the fibre helps digestion.
8g of fibre for very little. Between the beetroot, avocado and veg, this light plate quietly delivers a solid fibre hit that a GLP-1 gut appreciates.
Why I keep some lunches deliberately simple
There is a temptation, when you get into healthy eating, to make everything elaborate. But some of the most useful meals in my week are deliberately simple, and this is one of them. When I am busy or my brain is fried, a complicated recipe is a barrier, and barriers lead to bad choices. A salad I can build from four things in five minutes is a salad I will actually eat, and consistency is what matters far more than any single impressive meal.
The honest limitation here is protein — at 6g this is a light plate, not a muscle-protecting meal on its own. So I am always upfront that this is a lunch to build on or to balance against a protein-heavy rest of the day. But as a fresh, fibre-rich base that takes no effort, it earns its place. Not every meal has to be a hero; some just have to be easy and good, and this is both.
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 | ~260 kcal |
| Protein | 6g |
| Carbohydrate | 20g |
| Fat | 18g |
| 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 handfuls of crisp lettuce or mixed leaves
- 2 cooked beetroot, diced
- ½ avocado, sliced
- 8 cherry tomatoes, halved
- ¼ red onion, finely sliced
- 1 tsp olive oil
- 1 tsp balsamic vinegar
- Salt and black pepper
- Optional: a scatter of mixed seeds or some crumbled feta
How to make it
- Arrange the lettuce or mixed leaves in a bowl as the base.
- Add the diced beetroot, avocado, tomatoes and red onion.
- Whisk the olive oil and balsamic vinegar with salt and pepper.
- Drizzle over the dressing and toss gently.
- Scatter with seeds or a little feta if you want more substance, and serve.
- That is it — fresh, colourful and ready in five minutes.
Turning it into a proper meal
At 6g of protein this needs building on to be a main meal, which is easy:
Add a protein. Grilled chicken, a tin of tuna, two boiled eggs or some chickpeas all turn this from a side into a satisfying lunch.
Add feta or seeds. Either adds a bit of protein and makes it more filling while keeping it vegetarian.
Serve alongside a protein. It makes a brilliant fresh side to some grilled fish or chicken. See how much protein per day.
The five-part formula for a salad that fills you up
I keep coming back to this because it is the single most useful thing I know about salads. A salad that leaves you hungry is missing something; a salad that fills you up has all five parts. One: leaves or veg for volume. Two: a protein to keep you full — this is the one most people skip, and it is why their salads fail. Three: a healthy fat like avocado or seeds for staying power and flavour. Four: something with a bit of substance, like beetroot or beans. Five: a proper dressing to bring it together. This particular salad nails four of the five straight away and just needs a protein added to be complete. Once you see salads through this five-part lens, you will never build an unsatisfying one again, and you will never need to follow a recipe either.
Prep the parts, dress fresh
Leaves are best kept crisp, so this is one to assemble fresh, but the prep is minimal — keep cooked beetroot and cut veg ready and it is a two-minute job. If taking it to work, keep the dressing and avocado separate and add them just before eating so nothing wilts or browns. A quick, fresh option for my meal prep ideas for Mounjaro.
How it fits a full day of eating
This is a light, low-protein lunch, so it only works if the rest of my day carries the protein — a solid breakfast from my high-protein breakfasts and a proper high-protein dinner, or a protein added to the salad itself. On its own it is more of a fresh side than a main meal, and I am honest with myself about that.
Add chicken, tuna or eggs and it becomes a complete lunch. Otherwise I make sure high-protein snacks or a protein-heavy dinner fills the gap, with a protein shake as a backstop. The GLP-1 rule always holds — hit your protein across the day. My complete GLP-1 guide shows how.
No appetite today?
Fresh and light, a few forkfuls of this are easy to manage when your appetite is low, though it is short on the protein you most need — so pair it with something protein-rich if you can. When cooking or assembling is too much, HelloFresh keeps ready meals coming. More in what to eat with no appetite.
Supplements that pair well
As a fresh, fibre-rich plate this pairs well with a probiotic like Pre + Pro 15 for gut support. Because it is light on protein and omega-3, I make sure the rest of my day covers protein and I take Super Omega-3 EPA. The free Lily & Loaf lifestyle analysis can match a routine to your goals.
Frequently asked questions
Is this enough for a full lunch?
On its own it is light — more of a fresh side at 6g of protein. Add grilled chicken, tuna, eggs or chickpeas to turn it into a satisfying, complete meal.
Can I use pre-cooked beetroot?
Yes — vacuum-packed cooked beetroot (the plain kind, not pickled in vinegar) is a great time-saver and what I usually use.
How do I stop the avocado browning?
Add it just before eating, and a squeeze of lemon or the balsamic helps slow browning. If prepping ahead, keep the avocado separate.
Is this good for weight loss?
As a light, high-fibre, low-calorie plate, yes — just remember to add protein so you are not missing the muscle-protecting element a GLP-1 day needs.
Can I make it vegan and still filling?
Yes — add chickpeas, a scatter of seeds, or some marinated tofu for plant protein, and it becomes a filling vegan lunch rather than a light side.
The bottom line
Beetroot, lettuce, avocado and tomato salad is the fresh, no-fuss lunch for busy days — vibrant, 8g of fibre, and ready in five minutes. It is deliberately simple, and simple is what actually gets eaten. Just remember to add a protein — chicken, tuna, eggs or chickpeas — to turn this fresh base into a complete, muscle-protecting meal. To match your supplements to a light, fresh diet, 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.
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 lunches like this were a real part of how I held onto muscle and kept the weight off.
