TUNA NOODLE CASSEROLE
With the war rations and Great Depression officially behind us, the 1950s became a veritable casserole city. Tuna noodle was a signature, and since it had veggies, it sometimes spared kids from a common(ly reviled) side dish of the era: lima beans. If you got dessert, it was almost definitely gonna be a Jell-O "salad" with a whipped topping. In fact, these treats were so in vogue that Jell-O took things too literally and marketed gelatins with actual salad flavors, like celery. You don't see them around today for a reason.
