Creating Green Chili Chicken Enchiladas can be straightforward if you follow these simple steps:

1. Preheat the Oven: Preheat your oven to 350°F (175°C).
2. Cook the Onions: In a skillet, heat olive oil over medium heat. Add diced onions and sauté until translucent, about 5 minutes.
3. Mix Filling Ingredients: In a large bowl, combine shredded chicken, diced green chilies, sour cream, half of the shredded cheese, garlic powder, cumin, salt, and pepper. Mix well.
4. Prepare Tortillas: If using corn tortillas, warm them in a skillet for a few seconds on each side to make them pliable. Flour tortillas can be used without heating.
5. Fill the Tortillas: Take about 1/4 cup of the chicken mixture and place it in the center of each tortilla. Roll the tortilla tightly, folding in the sides as you go.
6. Arrange in Baking Dish: Place the rolled tortillas seam-side down in a greased 9×13 inch baking dish.
7. Pour Sauce: Pour the green enchilada sauce evenly over the top of the enchiladas.
8. Add Cheese: Sprinkle the remaining shredded cheese over the sauce.
9. Bake: Place the dish in the preheated oven and bake for 30-35 minutes or until the cheese is bubbly and golden.
10. Cool: Remove from the oven and let the enchiladas cool for about 10-15 minutes before serving.
