I suppose it depends when you went to school, mainly in the '60s for me, when Britain was probably still in the "brown gravy and lots of lumps in white food time warp" I hated most of what they served up with a few exceptions. The things I liked were few and far between, I remember we all loved the chipolata sausages, ruined by the accompanying lumpy mash. I also remember a lemon cakey thing served along with what we all described as "shaving cream", a foamy fake cream, that was a favourite. Jam tart and jam puddings good, ruined by being smothered in the obligatory lumpy custard. There was a prevailing smell of over cooked cabbage hanging about our canteen that wasn't very nice. Broccoli, where was that hiding back in time? nevertheless as al dente, as far as green vegetables were concerned was a concept yet to be discovered back then, even if it had been around, it would have no doubt been ruined by the "boil the guts out of it" school of cuisine
