If you find yourself needing to prepare a casual meal but you still want to impress an audience, or just enjoy the taste of something amazing, this is the sandwich to try. It’s a bit messy to eat but you’ll enjoy licking all the flavor off your fingers. The sandwich is fairly easy to make but looks super complicated and the taste will blow your mind.
I developed this sandwich based on north african and middle eastern dishes, with regional favorite white cheeses, that’s why I call it The Casa Blanca. The sumac is a great addition to sautéed onions, adding a tangy/smokey taste to the onions. The cheeses were chosen for their use in the region and are used in the order specified to optimize melting and holding the ingredients together. This grilled cheese is a little difficult to flip, so I did the frying in a covered sauce pan to help the cheese melt and start holding the ingredients together
