Our elementary principle's family owned the local bread bakery, so we always had dinner rolls. Still remember how they tasted. Salisbury steak and some kind of fried meat patty with gravy is about all I remember.
The first time school offered hamburgers was when I was in the 5th grade. Not like anything I had/ave ever tasted.
For the most part I took my lunch. Lots of deviled ham and vienna sausages.
