Look at where you can get 'more bang for your buck' when it comes to meat.
Chorizo for example, not cheap but you only need a small amount because it's so flavourful. Cut into small lardon sized bits, fry off with some red onion and chillies. Then add egg to make a spicy scrambled egg. Have it in wraps with some wilted spinach and fresh finely chopped spring onions.
Bacon lardons or ham offcuts from the cooked meat section added to a pasta bake make a very meaty flavoured bake but a lot cheaper than mince or chicken breasts. Can use ham offcuts in a quiche or a pie too.
We used to make a lot of chillies using whatever we could get cheap, sausages work surprisingly well, just brown them off then chop up and add to a chilli base (tomatoes, spices, beans, onions).
One pan roasts are good for sausages too, just put the sausages in a big roasting pan with any of the stuff you like - diced potato, parsnip, carrot, onion, mushrooms, cherry tomatoes, cauliflower, broccoli...... add a glug of oil and some seasoning/herbs. Then let it roast for an hour, giving it a good shake every now and then so everything goes brown and crispy.
If you have a butcher near you that does the big trays of pork chops/loin steaks/chicken thighs/drumsticks on 2for £xx offers, buy those, break them into portion sizes and into ziplock bags then add a marinade (honey & mustard, bbq sauce, soy, ginger and lime etc) then freeze. They marinade as they are freezing and then defrosting. Take them out the night before you want to eat them then onto a baking tray and into the oven and serve with baked potato/rice/corn on the cob/roasted broccoli or cauliflower/ cauliflower cheese.
