Sir, this is unpopular opinions about food.Kind of a no-brainer, but those pizzas you'd find in schools with the overly sweet sauce, not-cheese "cheese", and overly flour-y, flavorless crust are disgusting. I never ate another slice after the first one I had.
Also, fuck the school roast beef. That stuff's way too salty for human consumption.
In all seriousness, school lunch is average at best and inedible at worse. Save a couple dishes.
The only good frozen pizza brand is Ellio's. French bread pizza is alright.
