I hated school dinners at primary school and for years I wouldn’t eat cabbage, swede, mashed potato or stew of any kind aa they were ,respectively overcooked and watery, tasteless, lumpy with black bits in and greasy & gristly. I cant remember having anything else there but I pleaded with my parents to fo home to dinner & eventually they relented.
At secondary school it was a bit better especially the puddings which I generally liked. My favourites were treacle tart ((with crushed cornflakes), manchester tart, chocolate sponge - all with custard. Wasnt so keen on the sago.
I seem to remember having some sort of questionnaire at one point and lots of us asked for chips, after which we had them about once a week. But no-one had heard of pizza then!
