Duchesse
When school catering contracts were put out to competitive tender in the private sector, many were won by contractor companies who deliver food that just needs warming in a cabinet.
Therefore schools had a redundant room and were forced to put it to use.
The school at which I was a governor halved the size of the kitchen to make two study areas for SEN kids.
If they then are expected to provide twice as many meals, they will have to use cook chill methods as there is not enough physical space to cook from scratch.
And where do kids eat?
Well, at DCs secondary, the hall seats 400 - which leaves 1100 eating in tutor rooms, stairwells, corridors, playgrounds etc etc
to build a space big enough to hold all 1500 at once would be a daft waste of resources
