Just for the record, school lunches at DDs Scottish state primary school are extremely good. The HT eats them as well. I'm getting just a tiny bit tired of people saying school dinners are bad. Some school dinners are bad, no doubt, but not all. Please don't tar them all with the same brush.
A baked potato with a cheese filling (say) and a flapjack sounds pretty filling to me, depending on the size of the potato. Perhaps not perfectly balanced, but certainly filling.
As for the kids who only have two choc biscuits – it could be because that's all they'll eat and parents have discovered this over time and don't want to 'waste' other food on them which will only come back home uneaten, or it could be that they've eaten the rest already at morning break. I've come across both scenarios. One of my good friends at secondary school used to bring sandwiches. She was always dieting (and always hungry). She used to eat the sandwich fillings and give the bread to me at morning break. Then she would have nothing, or not much, at lunch time and I would have a school dinner. I'm pretty sure all of this and more still goes on.
The school dinners I had in the sixties and seventies were fine. Well cooked and good straight forward food. No complaints from me.
Sorry. Back to thread. Just trying to chuck in some balance. I'm sure plenty of kids are perfectly well fed on school food.
