As of Alpha 9, Players can assign inmates to do "Jobs" in kitchens (1/12m², max. 20), as well as other areas of the prison.
It is prudent to designate the kitchen a staff only area, if you have unlocked "Deployment" via Bureaucracy. This will prevent theft of tools/contraband, the potential escape of prisoners assigned to work there and also will prevent an optional route around any Metal Detectors you have installed at the canteen. However, keep in mind that prisoners cannot work at a kitchen marked as staff only.
As of Alpha 14, deliveries can be moved inside the prison and secured. So having prisoner jobs in the kitchen is no big risk anymore.
