Assemble the Mini Tacos:
Take each mini taco shell and fill it with a spoonful of the seasoned chicken and vegetable mixture.
Repeat this process until you have filled all the mini taco shells.
12 mini taco shells
Air Fry the Mini Tacos:
Preheat your air fryer to 400°F (200°C).
Place the filled mini tacos in a single layer in the air fryer basket. You may need to cook them in batches, depending on the size of your air fryer.
Air fry for 5-6 minutes or until the mini tacos become crispy and golden brown. You may want to check them halfway through and rotate if necessary for even cooking.
Serve and Garnish:
Remove the mini tacos from the air fryer and place them on a serving plate.
Garnish with your choice of toppings, such as diced tomatoes, shredded cheese, shredded lettuce, sour cream, and salsa.
