So simple to make and they don't have to be your typical cheddar cheese Mexican quesadillas. The sky is the limit on the permutations you can make on this basic flat bread cheese sandwich. This one is made with gruyere cheese and roasted red peppers. That's it! That and some flour tortillas. I like to use a bit of butter and a heavy cast iron pan to make my quesadillas. They come out delicious and crispy. The combination of a flavorful cheese with the roasted peppers was wonderful.
