This thread is very interesting.
I'm a cook at a elementary school, and I'm surprised that some of your kids only have a choice of two lunches.
Our schools offer the main lunch, which usually includes a hot item, some kind of potato, a vegetable, a dessert, fresh fruit and milk.
Every day, our kids also have a choice, if they don't want the main item, to substitute either a hamburger, cheeseburger, hot dog, bologna & cheese, peanut butter & jelly, a mini chef salad, hoagie, or fresh fruit platter. They also get the rest of the lunch menu items.
Not a bad deal for $2.10!
