Do not confuse this with the quesidilla, that’s totally different. This is usually made with Mexican string cheese known as Oaxacan. It’s similar in texture and color to mozzarella, but tastes a bit saltier. If you can’t find it, use any string cheese.

1 hard roll
butter
1 slice of ham
1/2 cup shredded cheese
1 fresh or pickled jalapeno
onion slices tomato slices
avocado slices

Half the roll and assemble the sandwich with the listed ingredients. Melt about 1 tbsp. of butter in a heavy skillet over low heat. Place the sandwich in the skillet while pressing down with a spatula or another skillet. Heat about 30 seconds on each side until the cheese has softened but not quite melted. This can also be heated over a backyard barbecue. Serves 1.
