Our school has been selling Market Day for three years now. Some stuff is good, and some I wouldn't buy again. The things I consistently buy are: Lasagna roll-ups (with and without the spinach), twice baked potatoes, apple blossoms.
My mother loves the breakfast quesadillas.
The things that didn't go over well: the cheese omelets, breakfast bundles (sausage, wrapped in a pancake, on a stick), the breakfast burritos.
