We do a big ASDA shop about every 10 days with top ups in between for like produce, bread, and milk. We spend about £50ish give or take depending if we need to buy toiletries or other home essentials that have run out.
Things we eat: eggs, cans of mixed beans and chopped tomatoes, pasta, pre seasoned cous cous, cheese, yogurt, nuts, juice, milk, mince, chicken fillets, fishcakes or fresh fish, rice, apples and clementines, onions, garlic, salad, pasta and curry sauce, just to give an idea. We don't buy any prepackaged meals and I think that really helps us to save money.
online_girl, my husband and I like to have a few beers during the evenings, but we buy the chosen by ASDA 12 pack of the little bottles of De Luxe Biere for like £6(unless we feel like splurging for the weekend on a particular brand). It's not amazing, but we both like it and the smaller bottles are nice.
