This is not so much a recipe as it is a technique of preparation. I tried it for the first time today and it worked well. This method was just an experiment. More thought to ingredients will be given the next time I make the quesadillas.
I used large flour tortillas and filled them with thin slices of ham and a mixture of grated cheeses. I spread a mixture of mustard and mayo on half of each tortilla. Then the ham was layered on the spread followed by the grated cheese. Next the other half of the tortilla was folded over the filled half.
Each of the filled and folded tortillas was laid on a preheated panini maker and grilled. It does not take long for the cheese to melt, so be careful not to burn the tortilla. Remove the quesadilla from the panini maker to a plate or cutting board. Cut each quesadilla into 3 wedges and serve either yourself or a crowd.
Take into consideration that this is more about method than recipe, and fill the tortillas with ingredients that you desire. Just don't over do it.
