Re: "I bet the lunches at the council offices are better than they serve the kids."
I was getting school dinners in the 60s and it was good, solid, wholesome food; although seldom any choice.
Minced meat on Mondays (local butchers getting rid of unsold meat from previous week) usually in the form of cottage pie or similar. Very occasionally lasagne (twice a year?).
Tuesdays would be chicken; usually roasted, very occasionally they would produce a stange watery tomato sauce and vegetables.
Roast Beef / Pork / Lamb on a Wednesday; served with roast potatoes and mixed veg. Sometimes with yorkshire puddings.
Stew normally on Thursdays, usually with dumplings that could be used in hand to hand combat; solid little lumps that really filled you up. I also remember having some Toad in the hole that was actually really good.
Fish on Fridays, normally steamed, very occasionally deep fried, sometimes with chips, otherwise boiled potatoes.
We were offered salads during the summer, but they were very basic; lettuce cucumber and tomato. No dressing or coleslaw. Normally with sliced cold meat, and my favourite was corned beef which most other kids turned their noses up at.
Almost every day we were offered a sweet pie or pudding for afters; and almost without exception it would be smothered in custard (which I hated). The only drink offered was water, which was supplied in large dull coloured aluminium jugs, which we drank from matching dull coloured aluminium cups.
Like yours, our dinner ladies took a pride in their work, and produced good food on a tight budget. But locally produced and sourced food.
