We spend about £110/week on 2 adults and 1 DC. That does not include our two cats who we have to order specialty food for as they have some medical issues 2 bags of food every 3 months for the cats is £80! We also eat out at least 1 day a week. On top of that we do a major Costco staples shop once a month for £175 (boxes of wipes, nappies, meat, etc). This does not include alcohol as we seldom drink, but will include a couple of newspapers and a magazine in the shop.
However we do eat well and I have seen some of the menu plans for the meals that involve serious food budgeting and they are usually things that would never be eaten in my household.
An example of our meals during the week:
Monday - BBQ - Rack of Ribs for hubby, pack of Organic beef sausages for DC and me. Marinade for Ribs. Salad (Advocado, tomato, onion, rocket, homemade dressing), Jacket potato with butter and sour cream
Tuesday - Falafel wraps -Falafels, Homemade Tztatziki, mixed leaves, cabbage, carrots, lemon
Wednesday - Turkey Stir-fry - Turkey breast strips, bok choi, garlic, ginger, onion, pea pods, water chestnuts, mushrooms, bean sprouts, soy, chili. Rice with egg, peas, spring onions and Shaoshing Rice wine.
Thursday - Pork fillet for hubby, Beef Fillet for DC and I. Homemade herb butter. Baby asparagus with Hollandaise. Potato Dauphinoise.
Friday - Homemade burgers topped with mushrooms and cheese. Oven wedges.
Saturday - Eat out
Sunday - Roast organic lemon chicken, Roast carrots, onions, potatoes. Homemade Yorkshire puddings. Homemade stuffing (bread, celery, mushrooms, onions, fresh herbs). Homemade gravy.
So this is an example of our meals for a week, an impossibility on a small budget. An organic beef fillet steak cost £7.00 for 1 and I am buying 2 and pork for hubby that is about £18 on meat for 1 meal alone...not to mention the other stuff that goes with it.
I also shop around and buy stuff at a range of supermarkets including Lidl.
I think it is all relative on what you like to eat. There are other things I would sacrifice before good food.
