That include takeaways + takehome booze guys? :)

Many moons ago, iwas divorced after 30 good years and my gf gave me a book called "How to Boil an Egg" which I took to Venezuela where I worked for 12 months (not highly paid).
I now live with gf and I still use it in my dotage and is still available on Amazon (that was about 7500 moons incidentally). One can eat very well indeed on 10USD, 6GBP per day, buying fresh veg and avoiding pre-prepared food. Not really enough to eat out occasionally altho fish'n'chips can be had for about 4 quid.

The average amount of food must be £200 to £250 but after that i also mention that it depends on the person too.

I work in central London and do buy lunch out a bit, plus going out quite a bit. However I give myself a daily budget of £20 which is for all food, going out and shopping such as shampoo, buying friends birthday presents, books etc. (basically everything after my bill are paid). Last year (before a promotion) it was £14 a day and that was certainly doable if I spent less on lunch and went out a bit less.
Would this budget include travel? (mine doesn't).
Personally I wouldn't go below £14 a day which is £420 a month but to cover everything I've listed above. I think this fits in with £200-£250 a month for food.
Having said all that if you only want to pay for basic food, and get her to get a job for the rest (which is what my parents did) then £250 should be fine.

£150 a month is what I spend and I live in London. If someone eats out then the sky is the limit. What does she know about cooking and nutrition?
@14 at school she cooks a lot of frozen vegetables, pasta, frozen meatballs (she doesn't cook meat) and jarred sauce. She buys brie, baguettes, carrots, turkey (lunch meat), hummus, etc.
Well if she's not that much into meat, it's probably more like £160-180 a month then. Depends where she sources from. If she finds (and uses) the local markets, that'll keep her costs lower than Tescos, Waitrose or M&S would.

A key feature in eating cheaply is discovering what time local supermarkets reduce prices of food with use by / sell by dates on that day. Often in evenings (or approaching closing time of usually 5pm on Sundays), but sometimes in mornings. For example, around 2pm today (Sunday) I bought a 200g tub of Asda own brand humous for 30p, reduced from 95p.
