Ok I am assuming you have tea, coffee and dried herbs in cupboard.
Jacket potatoes X 6, big block of cheese, baked beans, bread x2, mince, tinned tomatoes, red lentils, passatta, tomato puree, pasta, ham, milk, veg, porridge oats, spread, apples X 2 bags, fresh tomatoes.
Breakfast everyday porridge oats made with water and add a little milk or toast and spread.
Lunches You can make pancakes twice with 4 eggs roll up with ham, + apple
Jackets with baked beans + apple
Cheese and tomato toasties + apple
Snack ham sandwich, slice of toast, porridge
Dinner
Spagetti Bolognese with mince, onions, lentils, passatta, chopped up veg to bulk it out, herbs and pasta two meals
Oven baked cheesy pasta bake with breadcrumb topping and Veg two meals. Make with a roux ( butter, flour, milk, salt, pepper) add cheese and 1/2 teaspoon of dried mustard. Cook lots of pasta put in large oven bowl, pour over roux sauce and top with grated breadcrumbs.
Easier to make 2 big meals and stretch them to 2 meals than make 4 different meals.
Always good to keep a few tins stashed away for weeks when not much money to spend, tuna, corned beef, tomatoes, pesto.
