The National Sandwich Idea contest was held between 1956 and 1981. It was sponsored by the Wheat Flour Institute. Each year 20 sandwich recipes, created by Food Service professionals, were chosen as the top sandwich recipes from hundreds of entries.

The All-American Sandwich was the number #1 recipe chosen in 1959.

It was created by Laure B. Hale of Tulsa, OK. She was a cashier-checker
at the Tulsa YWCA.

The All-American Sandwich is a three-decker with egg spread, ham, cream
cheese spread and avocado spread between four slices of bread.
