One Trolley, Five Lunches: The Supermarket Prep Plan for Busy Workdays

Most weekday lunches don't fall apart because you lack discipline. They fall apart because it's 12:40, you're hungry, and the nearest meal deal is right there. The fix isn't a heroic Sunday spent cooking eight identical chicken breasts. It's a small, repeatable shop and a bit of component prep that makes the easy choice the decent one.

This plan is built around one £25 supermarket shop and five workday lunches. It uses ordinary ingredients, assumes a normal kettle-and-hob kitchen, and leaves room for the fact that some days you'll be eating at your desk and some days you'll be eating in a staff room that smells of toast. At PW Fit, the goal is real training for real lives, and lunch is part of that.

The £25 baseline shop

Prices move around by store and region, and they definitely move between Aldi, Lidl, Asda, Tesco and Sainsbury's. Think of this as a shape rather than a rigid receipt. If you already have oil, salt, pepper and a few spices, you're ahead.

• 1kg long-grain rice — around £1.20
• 6 wholemeal wraps — around £1.10
• 2 x 400g chicken thigh fillets — around £4.50
• 6 eggs — around £1.50
• 1 tin tuna — around £1
• 1 tin chickpeas — around £0.60
• 400g Greek-style yoghurt — around £1.20
• 200g cheddar — around £2
• 1kg carrots — around £0.60
• 2 cucumbers — around £1.20
• 6 tomatoes — around £1
• 2 onions — around £0.30
• 1 head broccoli — around £0.70
• 1 bag frozen peas — around £1
• 1 bag spinach — around £1.20
• 6 bananas — around £0.90
• 6 apples — around £1.50
• 1 jar passata — around £0.80
• 1 jar wholegrain mustard — around £0.80

That comes to roughly £23, leaving a couple of pounds for a stock cube or a bag of frozen sweetcorn. If you don't eat meat, swap the chicken for a second tin of chickpeas and a block of firm tofu if your budget stretches. The rest of the plan still works.

Sunday, 30 minutes, no performance

Preheat the oven. Put the chicken thighs on a tray with sliced onion, a little oil, salt and pepper. Get the rice on. While those cook, chop cucumber, tomatoes and carrots. Make a quick dip with yoghurt, a spoon of mustard and a splash of water. Boil the eggs while the rice is bubbling.

When the chicken is done, slice it and let it cool. Store everything in separate containers: rice in one, chicken in another, chopped veg in another, dip in a jar. Use five containers or five bowls with plates on top. You're not building five finished meals; you're building parts. That's the difference between a prep session that takes half an hour and one that swallows your Sunday.

The five-day mix-and-match

Monday: Chicken, rice, spinach, grated carrot and a spoon of the mustard yoghurt. Warm the rice and chicken, keep the spinach raw and let it wilt slightly under the hot rice.

Tuesday: Tuna, chickpeas, cucumber and tomato in a wholemeal wrap. Mash the chickpeas a little with the yoghurt dip so it holds together.

Wednesday: Egg and cheese wrap with spinach and tomato. If you boiled the eggs on Sunday, this takes two minutes. If you didn't, scramble two eggs in the microwave at work and accept that it won't be pretty.

Thursday: Chicken, passata, rice and frozen peas. Warm it all together until piping hot. Add a little cheese on top if you want it to feel like a proper meal rather than a container of components.

Friday: Chickpeas, passata, spinach and rice, with a spoon of yoghurt and a little grated cheese. If you have leftover broccoli, throw it in. This is the fridge-clearing lunch, and it's usually better than it sounds.

The meal-deal trap is a design problem

Meal deals aren't evil. But a £4 or £5 lunch plus a snack and a coffee can quietly become £30 or more a week. The point isn't to never buy lunch. The point is to make the default lunch already in the fridge, so buying lunch becomes a choice rather than an emergency.

Keep a backup at your desk or in your bag: a tin of soup, a couple of oatcakes, a banana. If you forget lunch, buy something and move on. One bought lunch doesn't undo the week.

Make it survive a real week

Cook rice in a big batch, cool it quickly, fridge it and reheat until piping hot. Don't leave it sitting in a warm office all morning. If you're not sure about something, use your nose and your common sense.

Swap the chicken for leftover roast meat, the tuna for more eggs, the spinach for frozen peas. Buy the wraps that are actually on offer. The £25 figure is a target, not a test. The real win is having five decent lunches waiting for you when the day gets busy and the meal deal starts calling.
