Grilled Quesadillas

Ten years ago, few of us had heard of quesadillas. Now we can’t seem to live without them. These Mexican grilled cheese “sandwiches,” made from chiles and cheese sandwiched between tortillas, have taken the United States by storm. Most are panfried, but this recipe features a quesadilla that’s actually cooked on the grill. Feel free to vary the ingredients for the filling, but don’t wander away when cooking them. Tortillas burn like paper.
