I agree with Rachel. At our elementary school the PTA gets volunteer parents to take over lunch and recess for the classes so that the team can have a 1 hour lunch break with good food. Sometimes the food is catered, sometimes volunteers bring it in. They set up and decorate a nice area in the school with pretty table cloths, etc and make it a special lunch.
Also, for teacher birthdays, volunteers will take charge of the classes for lunch/recess so that the teams can have a birthday lunch as a group.
I do know that the special unrushed lunch is welcomed.
