When I was in gradeschool, lunch was like prison. We got a tray with various dents in it and each dent got a scoop of something. Desert was either jello or pudding except on fridays, then it was either a small square of yellow cake or a scoop of cobbler of some kind.
When I went to public school in NYC in the 1960s, Friday's were fish sticks for lunch.
I bet you can't get away with that today, what with the focus on "separation of church and state."
