From what I gather after the fact, it was my DS's chosen mission in high school life to expand the mealtime horizons of his classmates. Hence 'field trips' to New York style delis, Mexican, Italian, Greek, Cajun, you name it.
He and his buddies got away with it by a fluke of scheduling. They had their 'free' period just before lunch and at least two teachers who had classes after lunch had a policy of taking attendance at the end of class instead of at the start and counted class participation as being present to turn in homework. (Methinks there was some bribery involved there, like bringing lunch back for the teacher.)
For that matter, one of those teachers gave DS an A for class participation even though he was asleep in class. DS didn't snore, his homework was in and he wasn't being his usual obnoxious self.
