when does a grilled cheese become a melt
Melt sandwich One common filling is tuna with mayonnaise; the result is a tuna melt sandwich. Other popular choices are ham, roast beef, chicken, turkey, or a hamburger patty, which is known as a patty melt. It is the filling that establishes the melt sandwich as a variation of the grilled cheese sandwich. Patty melts were a staple of the traditional U.S. diner and were commonly found on menus as far back as the 1950s and possibly the 1940s.
