If you are very careful with these assembled patty melts you can cook them on the grill. Otherwise cook them in the skillet you cooked the chile mixture in, just wipe it out & heat it before cooking the patty melts. Or you can put them on a broiler pan & broil in your oven. When the patty melts are done. Spread some of the Chipotle mayo on both sides of the bun, place a slice of cheese on the top half of the buns & add any other garnishes desired.
