Classic Tuna Melt

The tuna melt grew out of the classic tuna salad sandwich, which became popular in the U.S. after canned tuna was mass-marketed in the early 20th century. Adding melted cheese and griddling the sandwich became a diner favorite by the mid-20th century, turning a simple cold sandwich into a warm, comforting lunch.
