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 Hamdinger Sandwich was the number #1 recipe chosen in 1960.

It was created by Mr. and Mrs. F. Kenerson Johnson of College Park, MD. The Johnsons were owners of The Mobile Kitchens of College Park, an industrial catering service. The Hamdinger Sandwich weighs almost half a pound.
