When I was in grade school, every Thursday (or it seemed that way) we had chilli con carne and these giant cinnamon rolls. I don't know who ever dreamed up that combination, but at the time, it was heaven.
Another school favorite was Browned Beef in gravy over whipped potatoes.
My favorite dessert was the little cups filled with raisins, minature marshmallows, and salted peanuts. Yum!
