RECIPE PREP: Preheat air fryer to 400°F. Wrap corn tortillas in a damp, lint-free kitchen towel. Microwave for 30 seconds or until soft and pliable. Keep them wrapped. Set them aside.

1. Add shredded chicken, shredded cheese, diced green chilies (optional), and taco seasoning to a large bowl. Toss and stir to combine. If the chicken mixture is too dry, add a bit of chicken broth one tablespoon at a time until the chicken mixture is just lightly moistened. 
2. Unwrap the warm corn tortillas. Working with one tortilla at a time, spray both sides with cooking spray (or brush with oil). Place the tortilla on your work surface. Arrange 3 tablespoons of the chicken-cheese mixture down the center of the tortilla.
3. Roll the tortilla tightly, enclosing the filling. If the taquitos start to unroll, secure them with wooden toothpicks (it’s fine to air fry with wooden toothpicks in place, just remember to remove them before serving). Repeat the filling and rolling process with remaining tortillas and meat mixture. 
4. Arrange the rolled tacos in a single layer, seam side down, inside the air fryer basket. Make sure the basket is not overcrowded. Lightly spray the top of the taquitos with cooking spray.
5. Air fry at 400°F for 10 to 12 minutes or until rolled tacos are golden and crisp. Transfer taquitos to a plate and immediately sprinkle with flaky salt. Garnish with your favorite toppings.
