In the early 1990's Hardee's released the Frisco Burger.
Their version of a patty melt.
The 1/4 pound charbroiled patty, 2 slices of swiss cheese, tomato and bacon was served on a toasted sourdough bread.
The sauce is a bit of a mystery.
It may have just been mayonnaise or it could have been an onion mayo.
I have heard rumors about the sauce but nothing definitive.
I went with the onion mayo and it works well.
This really could use some extra help though.
The secret sauce from the Super Star/ Famous Star would be a great addition to this burger!
Hope this video brings back fond memories of this classic menu item from the 1990's.
Enjoy!
