From that I'd make: bolognaise, chili, roast chicken, chicken soup (with toast for kids), fish fingers, potatoes and veg, pizza with salad bits and salad leaves, eggs, beans and toast.
Porridge, scrambled eggs, pancakes, toast for breakfast.
Sandwiches, crisps, veg sticks, biscuits, fromage Frais, eggs of some kind, soup, basterdised carbonarra (mature cheddar and ham) for lunches.
I also make a load of cakes of some kind.
This is for 2 adults, 2 kids. I don't eat the rice and have a slice of toast or potato salad with chilli, as the rice won't stretch and I begrudge buying more. I s'pose I'd need a second pizza for an extra child too, so an extra 95p. This always comes out at around £50 when you split the every few weeks things over different weeks, I'd never buy all of them in the same week only across the month. I shop in Aldi, it's fairly easy. I could make it all a lot cheaper if necessary.
