This burger can also easily be made indoors in a frying pan or on a grill pan, then topped with the salami and cheese and broiled until cheese has melted. *All in the same pan if using an overproof or cast iron pan.(Buns can also be broiled to toast).
(You can double the sauce if wanting it spread on both the top and bottom buns, but we didn't think it needed it. And I'm a convicted double-dipper).
