Preheat the oven to 450℉ (232℃)
In a skillet, sauté the diced onion until softened.
Add ground chicken to skillet and cook through with the onions.
Stir in cumin, chili powder, garlic powder, and salt.
Mix in green chiles and salsa verde. Reduce heat and simmer on low while shredding the cheese (you could also used pre shredded cheese and skip the simmering step to save time).
Warm the tortillas (microwave or lightly fry) until soft and pliable to prevent cracking.
Spray the baking sheet with avocado oil.
On one side of the tortilla, place a few tablespoons of the chicken mixture and sprinkle with cheese.
Fold the tortillas into tacos, arrange on the sheet, and lightly spray the tops with oil.
Bake for 8 minutes, flip tacos, then bake for another 6-8 minutes until crispy and golden.
Serve hot with your favorite toppings (sour cream, guacamole, salsa, cilantro, lettuce).
