I tend to use lots of fresh ingredients, and a few tins.
Until three years ago I lived on ready meals and takeaway, and never cooked anything more demanding than a baked potato with melted cheese. My shopping was all tins and packets, with maybe some apples from the fresh section.
Then almost overnight, I started cooking, and it really has changed my life. I buy tinned tomatoes and kidney beans, and sometimes chick peas (I prefer dried chick peas and kidney beans, but sometimes I want the tinned ones there for when I'm in a hurry) and I do buy some frozen veg (peas and sprouts and broad beans are fine frozen, I find, and are nice and easy to add to casseroles and risotto etc) but nowadays I'd say that 80% of my shopping is fresh fruit and veg. Very occasionally, if I'm feeling tired and lacking energy, I'll buy a pizza base and some veg + tomato paste, and make a pizza, but I don't think I've had a ready meal in ages. I don't cook every night - I tend to do big batches of stuff and freeze portions - I might make a big batch of chilli or casserole one night, eat some that night, have some for leftovers tomorrow, and freeze some for two other nights another time. I cook an actual meal from scratch maybe every other night, or every three nights, but I eat my own cooked food every night.
