Skirlie by Charles Barron

Set in a school canteen something strange is boiling in the kitchens we take the lid off the pot and youll never feel the same way about school dinners again. The fascinating characters include 3 dinner wifies whose combined skills barely qualify them to use a tin opener thats if they could find one.
The teachers are more concerned with their private lives than the education of the pupils and a cleaner whose appearance causes some concern. Add a catering supervisor to the menu and the comic situations culminate in a surprising climax
