what you spend on food depends on a few different things:
- how much you can cook/can be arsed to cook
- whether youre a fussy person who won't eat non-brand stuff
- if you like little luxuries
I would say, if you're willing to cook from ingredients, rather than buy ready made sauces/meals etc, buy own brand or even basic/value stuff (it's all the same you know...) and dont buy ben& jerrys and stuff, you could probably budget £15 a week for food, but it will take you a while to adjust to knowing what to buy/how much to buy. I was spending stupid amounts at first and not even eating the stuff coz it was all going off before I could use it.
I would say budget £20 to start with, but once you get adjusted/learn to cook it will probably be less...
