There is 3 of us here , us in your 60's, mum in her 80's and I would spend very little on meals tbh, although we do eat well
I yellow sticker shop, cook from scratch and fill out the plates with veg
The other week Lidl NI had extra large chickens for £3;50, I squeezed as many as I could into the freezer
So one chicken - roast dinner for three
Sweet and Sour chicken and fried rice - loads bottom of the drawer veg - juilliane carrots, peppers, spring onions, shredded cabbage , sweetcorn - whatever
Chicken Curry and rice , add left over cauliflower florets and spinach , mushrooms if Ive got them
So 9 meals out of a £3:50 chicken
Veg, I buy seasonal, I buy what's going to go with a roast, and I buy the biggest of a single price item - say a cauliflower - Ill buy a huge one, there's at least 3 meals coming from that ( use the stalks in the cauliflower cheese - no one notices )
I also buy a lot of frozen veg
I also use beans and lentils to stretch a meal. A fav here for example is a sausage casserole, its really flavoursome , throw in a can of butter beans and every one is stuffed full with just 2 good quality sausages ( although I often use the packs of cocktail sausages reduced to pennies around Christmas )
I would say our main meals are around £2 a head
Today I picked up 500g of butchers mince for 2.50. That with a few handfuls of red lentils, half a bag of frozen mixed veg, an onion or two and some spuds will make cottage pie for six . 3 eaten tomorrow, 3 for the freezer for another day
We also eat a lot of salad veg in season. Which for me makes cooing easier and cheaper - I make quiches using left overs from sandwich ham , squidgy tomatoes etc . Even a smallish one will serve 3 and a small portion left for someone's lunch.
I make pizzas, wraps, risottos where very little meat is required
And I make good use of pressure cooker, slow cooker, air fryer and freezer
