Instructions:
Preheat Oven: Preheat your oven to 375°F (190°C).
Prepare Chicken Filling:
In a large bowl, combine the shredded chicken, 1/2 cup of green enchilada sauce, sour cream, half of the shredded cheese, and the chopped green chilies (if using).
Mix well until the ingredients are thoroughly combined. Season with salt and pepper to taste.
Assemble Enchiladas:
Lightly grease a 9x13-inch baking dish with olive oil.
Take one tortilla and spoon 2-3 tablespoons of the chicken filling into the center.
Roll up the tortilla tightly and place it seam-side down in the prepared baking dish.
Repeat with the remaining tortillas and filling.
Add Sauce and Cheese:
Pour the remaining green enchilada sauce evenly over the top of the rolled tortillas.
Sprinkle the remaining shredded cheese over the sauce.
Bake:
Cover the dish with aluminum foil and bake in the preheated oven for 20 minutes.
Remove the foil and bake for an additional 10 minutes, or until the cheese is melted and bubbly.
Garnish and Serve:
Remove the enchiladas from the oven and let them cool for a few minutes.
Garnish with chopped cilantro and green onions, if desired.
Serve with lime wedges on the side for a burst of citrus flavor.
