You know, the recipes for that kind of pizza are adaptable. A lot of how they come out is in the ingredients used. And not every school was/is supplied by the same distributors.
Our district was kinda mid. I had pizza at other schools for one reason or another both as a kid and as an adult. One district maybe two counties over (depending on how you define over) used the exact same recipe, but had a different food distribution contract and their shit was yummy rather than just better than nothing. But I also had some that was barely edible enough to choke down.
Seriously, go take a look at the recipes. There's nothing in them that has to give unpleasant results.
