We are a family of 5, DC are 5, 8, 10 so none in nappies etc. They take packed lunches to school & DH to work. I spend £40-£50 per week including toiletries, cleaning stuff.
I shop at Aldi & top-ups at Co-op (included in above sum). I would say we eat well. For breakfasts I offer cornflakes or Weetabix or porridge, with honey or fruit (I keep some berries in the freezer). Lunches are cheese spread/marmite sandwiches, salad, hm cake, basic fruit (Aldi super 6, apples, bananas, pears etc), sometimes crisps. Snacks are biscuits, hm popcorn, fruit, seeds, crackers & cheese, hm cake/flapjacks. Dinners can be cottage pie, casseroles, wm pasta, risotto, fishfingers, scrambled egg & baked beans, hm pies, fish pie, quiche, curry etc. All with salad & jacket, veg (broccoli, carrots, leeks, green beans, parsnips, cauliflower) & jacket, wedges etc. Variety of desserts, tonight is hm apple & BlackBerry crumble & custard.
So lots of home baking. Own brands unless not available (eg Marmite etc). No ready meals/ready made foods or individual portions eg if I give cheese in lunchbox I chop from large block, not individual plastic portions. Also hardly any waste, I freeze leftovers & we have a pot luck meal every few weeks, where everybody has different leftovers.
I buy reduced goods where possible, often bread, veg etc. No alcohol.
I have to shop this way because of our budget, but I'd probably do similar if I could afford more.
