OK buy a bag of potatoes, packet of rice
Kilo of mince, a whole chicken, a whole chorizo ring and salad bits (bag of leaves, cucumber, tomato, 2 peppers) and some wraps. Peas and carrots if you don't already have them. 2 pizzas from Iceland. Some cheap cheese (Iceland do a small block for £1)
All that should come to around £25 if you buy the cheapest option. Not always ideal, but a week of slightly lower quality meat etc never hurt anyone.
You already have pasta, tinned toms and Mexican beans.
Chop up chorizo and dry fry, add tin of toms and season (won't need much salt, but pepper and mixed herbs will do) cook the pasta and mix it all up. Dreamy dinner for a few quid. And we always have enough left for lunch for at least one of us next day.
Jacket spuds with roast chicken and salad.
Leftover chicken for quesadillas with Mexican rice. So cook the rice, season and add half tin of Mexican beans (save the rest for tomorrow) Wrap topped with cheese, leftover chicken and chopped pepper, fold in half and dry fry or grill.
Half the mince, cooked with tinned toms, leftover Mexican beans and spices for a sort of chilli with rice.
Rest of the mince, cooked and then add some beef gravy (trust me on this), chopped carrots and peas and serve with mash.
Pizzas and salad.
That's 6 dinners.
I'm out of ideas for now, if I think of any more I'll be back
