Preheat a large skillet over medium heat
In a mixing bowl, combine the cooked black beans, corn, cilantro, spices, and salt and pepper to taste
Lay 3 corn tortillas on a flat surface, then spread an even layer of cheese over each tortilla
Spoon the black bean mixture over the top of the cheese
Top the bean mixture with more shredded cheese, then cover it with another corn tortilla
Repeat this process with the remaining tortillas
Brush the preheated skillet with oil and place each quesadilla in the skillet
Cook the quesadillas for 2-3 minutes on each side, or until the cheese has fully melted and the tortillas are crispy
Remove the quesadillas from the skillet and cut them into quarters. Serve them with your desired toppings.
