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 Canadian Mushroom Sandwich was the number #1 recipe chosen in 1973.

It was created by Fred Novotny, then president of "The Peppermill," Towne House Inn Inc from Morton, IL.

The Canadian Mushroom Sandwich consists of Canadian bacon, mushrooms, melted Swiss cheese and green (bell) pepper rings on a Kaiser roll.
