@FormerlySpeckledyHen , you were born after rationing ended. My parents and my friends' parents remember rationing.
In my childhood, meals were smaller, less varied, locally produced and home cooked.
@Gasp0deTheW0nderD0g , that sounds like a lot of food!
School dinners were awful. I was allowed to leave the mashed potatoes but was to eat everything else. I would eat what I could tolerate, then rearrange the large scoop of mash so that it covered the mound of food.
We usually had a pudding. Usually something like apple pie/crumble and custard . We didn't have a snack mid-morning. We had the rather warm milk.
We had names for most of the dishes we were served at school. I remember liking the ice cream, but we didn't have it often. If I never ate school dinner food again, it would be too soon.
I would make the effort to get away with eating as little of it as possible, which was helped by me being a slow eater anyway.
After school, we usually had a sandwich, usually thinly sliced bread with jam, and a small piece of cake.
I'm not much of a fruit eater and don't eat much food that is wheat-based (bread, pasta, cakes, biscuits) - I just don't see the point of it. (I had a mac'n'cheese pie recently and it was revolting. It had a yellow sticker on it and I thought I'd try it. If you haven't, don't)
Another difference I have thought of is the addition of butter and jam/marmalade to bread or toast. I was talking to a friend a few days ago and apparently people add butter to the toast before the peanut butter.
I often had a boiled egg for breakfast; we had chickens. If we had cereal, it was weetabix or shredded wheat. Regular milk and no sugar unless I wanted it (I didn't).
