Preheat the air fryer to 350 degrees.
Arrange some cheese on half of one tortilla. Top with the shredded chicken. Then add some fajita peppers, black beans, and corn. Finally, add some more cheese on top and fold over. Repeat until you have made the rest of the quesadillas.
Place 2 quesadillas in the air fryer basket and brush olive oil on top.
Cook for 4 minutes. Carefully flip and brush some more olive oil on top and cook for another 4 minutes or until the cheese is melted.
Continue until all quesadillas are cooked. Cut them in half and enjoy with your favorite sauce.
