We always had toast for breakfast, my mum and dad never really bought cereals as such only porridge - which I do like. In primary/middle I had school lunches and then high school I took pack - would have probably been something like ham or cheese sandwhiches, crisps and a biscuit.
On a Sunday we always had a roast, Monday was left overs, Tuesday was something like sausage and chips, Wednesday was a stew or say chops with mash and veg, Thursday was meat pie or say homemade fish and chips or spag bol and then Friday was an anything day as Mum and Dad went shopping went Dad got home from work so it had to be quick. Saturday was sort of like a treat tea, maybe curry or pizza.
Mum nearly always cooked from scratch and went to the butchers for meat.
One thing though, when something ran out say like fruit/biscuits/juice, we had to wait till the next shopping day, whereas I will just nip to Sainsburys half way through the week to top up. But then again, Mum does not drive so this made a huge difference.
