In a medium bowl, combine chicken, lime juice, cheese, salsa verde, diced chilies, cumin, and salt and pepper to taste. Mix well.
Place about 1/2 cup of the filling on the bottom 1/3 of a tortilla. Wrap the tortilla around the filling, folding the edges in towards the center as you roll. Place seam side down on a parchment lined baking sheet. Repeat with remaining tortillas and filling.
Preheat air fryer to 400 degrees. Spray the chimichangas with cooking spray.
Add 2-3 chimichangas to the air fryer, seam side down. Cook for about 8 minutes, turning once halfway through cooking, until crisp and golden brown. Repeat with remaining chimichangas.
Serve with lettuce, avocado, salsa, sour cream, etc. and other favorite taco toppings.
