 But there's a good reason they go to all this trouble. These pepperoni rolls are beloved in a way no other school lunch is. My friend and former co-worker Whitney Humphrey is 34 and graduated from Riverside High School in 2007. On pepperoni roll days, the teachers would let you out like five or ten minutes early so that you could get to the cafeteria because there was always such a long line. Because even kids who typically didn't eat school lunch would eat lunch on pepperoni roll day.
