Put the corn tortillas on a dish towel and wrap up. Heat in the microwave for 30 seconds to one minute until warm and pliable. Keep in the towel to keep warm.
Spread a heaping tablespoon of black beans on one half of a corn tortilla. Sprinkle with a heaping tablespoon of cheese followed by a tablespoon of chicken. Sprinkle with a teaspoon or so of green chilies. Top with another tablespoon of cheese. Fold over and press down, repeat with remaining tortillas.
While you make the rest of the tacos, heat the air fryer at 375 degrees for five minutes.
Place three to four tacos in the basket of the air fryer. Spray with non-stick cooking spray. Flip and spray the other side. Slide the tray back into air fryer. Cook for six minutes or until the cheese is melted and the tortillas are crisp. Repeat with remaining tacos.
