Actually I imagine some fantasy foodie
version of pizza might be pretty good for kids. You know, thin crust, quality ingredients, heavy on the vegetable toppings, real cheese, high ratio of toppings to cheese, relatively low (for pizza) salt content. Stick something resembling a salad on the side and we've got a meal. But the reality of public school pizza, unless it's changed a lot since I was a kid, is a slab of something resembling cheese on top of a slab of something resembling bread, a tiny bit of something resembling tomato sauce, and maybe something almost but not quite pepperoni.
