Having worked in a school kitchen (not cooking, but clearing up) meals look great on paper, but rarely live up to the hype. Portions are often small, combinations of foods are weird and last down to eat get hobson's choice!
On some days potatoes are hard and meat is overcooked. Some days I threw away huge quantities of uneaten food and had to ask children if they'd tried everything. The looks of disgust said it all, really. I wouldn't have eaten it either.
Food is unseasoned - no salt allowed, and puds look delicious but are sugar free, hence taste-free. Most school dinner kids get 1 meal a week that they actually like. The rest is either tolerated or chucked. Disgraceful really,
