The majority of our main meals come out at £5 maximum
Eg.
Sausage, mash, 2 veg and gravy comes in at £3 odd
Likewise pasta with tuna and tomato sauce with a little grated cheese about £3
Macaroni cheese with mixed veg again about £3
Shepherds pie about £4
Likewise spag Bol about £4
Roast dinner is only about £6
We mostly eat "untrendy" veg though. Peas and sweetcorn (frozen or tinned), cabbage, carrots, broccoli, cauliflower, leeks, Spring greens, swede, onions, potatoes.
I used to do "clean eating" and would spend double what I do now on avocados, mangoes, grapes etc. As well as things like almond milk and cashew nut butter and spirulina powder. I was honestly being ripped off so badly by the "superfoods" myth.
My weight has regulated, I've got better vitamin levels and my energy levels have improved since going back to Meat and veg type fare...
I can't believe how much money I wasted on quinoa when brown rice does basically the same job, or how much I spent on asparagus when peas and cabbage are just as good!
