Place a tortilla in a large non stick pan (no oil spray necessary) over low-medium heat. Add 1/2 cup pulled pork evenly to one half of the quesadilla. Add a scant 1/2 cup black beans over the pulled pork, making sure not to let them spill out of the tortilla. Top with 1/2 cup shredded cheese, distributing the cheese evenly over the pulled pork and the black beans. If you like things spicy, feel free to add a few slices of jalapeño.
