So I posted earlier on the thread- we spend around £100ish a week for 4 adults or £65 is for 2 adults when kids are back at Uni. And for that we eat really, really well.
Today DH and I did a "Souper Sunday" where we audit all the bits and bobs that need using up, then look up soup recipes (we have a fab box set of New Covent Garden soup recipes books that we picked up in a charity shop for £3).
Main things that needed using up were a lot of cherry tomates that were going a bit wrinkly, the leftover sweet potatoes from a bag I bought for a recipe, some carrots that were past their best and some excess parsnips. I also had a few half used pots of cream/crème fraîche/sour cream that I used in other recipes earlier in the week.
So we made Tuscan Bean soup, sweet potato, onion and corn chowder, carrot & ginger soup and parsnip and apple soup. About 24 lunch sized portions. Healthy, delicious, cost pennies and prevented food waste.
But as I said previously, I have the luxury of time, skills, headspace, storage space, no intolerances and no fussy eaters.
