The only whole items I've ever seen are lettuce, tomato, and apples. Wait, once they gave the kids a mango. They didn't know what it was, and they certainly didn't eat it.
Whatever your feelings are about the free/reduced lunch programs (or public school in general), set those aside for now... the only reliable meal that some of these kids have is the meal at school, and we're feeding them garbage. I remember my school lunches as a kid. They were delicious, fresh, and nutritious. Our lunch ladies cooked, they didn't just reheat; it was as though your grandmother was making your lunch.
