Slice chicken breast in half, season both pieces in taco seasoning, covering all sides.
All the chicken to the air fryer basket without overlapping and cook at 370 degrees Fahrenheit for 6 minutes. Open the basket and flip each piece, then cook for another 6 minutes.
Remove the chicken from the basket and let it rest on a cutting board for a few minutes, then cut into strips of shred. (Wipe the basket clean after removing the chicken)
Place a disposable air fryer basket liner, (or silicone liner or make one out of parchment paper) in the air fryer basket.
Place the chips in the bottom of the liner.
Sprinkle the chicken, cheese and black beans on.
Cook for 3-5 minutes at 350 degrees Fahrenheit or until the cheese is fully melted.
Add tomatoes, green onions and guacamole on top (and any other favorite toppings on as well).
Lift the nachos out of the basket carefully using the liner, place on a plate and enjoy!
