For each quesadilla, place a tortilla on a plate and evenly spread with cheese, black beans, corn, avocado slices, chipotle sauce, then additional cheese.
Heat a large non-stick skillet* over medium heat for a few minutes. Place the loaded tortilla on the griddle and add another tortilla on top. Cook until browned, then flip and cook until browned on the other side, a few minutes per side.
Remove the tortilla and cut into wedges with a pizza cutter. If making several quesadillas at once, keep them warm in a 300°F oven until ready to serve. Serve garnished with chopped cilantro and additional chipotle sauce.
