seafood I know! It just needs a glass of cold Chablis.
At prev school the 'cooked' lunches were awful. Often only bread was left but even if you were quick, it was 'mystery meat' of the lowest kind (turkey twizzlers, anyone?) and partly cooked oven chips, frequently. No salad, hardly any tinned veg, and a few hard bruised apples. 'Pudding'' was custard creams if they had them. Or the peer pressure froot shoot lunchbox stuff. Crisps outside in playground for snack. Scraps between kids who had no snack. My ds used to get his taken off him for years and the school head simply nodded and said (of kid taking the food) 'ah, yes, that child is never sent with food, that family has problems 
Now they get a homemade 2 course plus extras hot meal daily.
Snack is eg freshly made pancakes, fruit scones with jam, flapjacks etc. The cook comes into the kids design tech lessons and talks to them about nutritious food / how to cook. They grow veg for the local old folks centre in the school 'kitchen garden'.
During SATS week apparently they do a 'hotel style' cooked breakfast every day for the kids and the staff come in to join them. So the kids take their exams on a full stomach. This is not a Private School, or in an esp deprived area on some sort of scheme. I don't know how they've done it, but they have. Mine are currently on fsm. I am embarrassed. But HUGELY grateful too.
It is SO how it should be, for the future health of Society, I cant quite believe it.
