Yes....I wondered the same thing about the "nutritional value" of a school meal.....I'm thinking maybe I'll stop in at one of our local schools here (Auburn)....I don't have any kids in school.
If it's like the school we used to go into on occasion in Fulton, it'll gag you. Where we live now, not far from you if you live in Auburn, it's not bad. It doesn't have the stench, but there's not much of it and it's high in carbs and fat. Even my son, who will eat anything that isn't moving, has decided to take his own lunch after a few weeks of school cafeteria food. (This is his first year in public school, 10th grade.)
Our elementary schools lunches are not that great. It's just nice not to make lunches if my kids chose to eat at school.
My son just started middle school, and he loves the food there. He can get a cinnamon roll for breakfast or a snack, and they have pizza or quesadillas every day. He's super skinny so he can even eat the cinnamon roll every day if he wants to.
