Preheat your oven to 375°F (190°C). Lightly grease a 9x13-inch baking dish with cooking spray.
In a large mixing bowl, combine the softened cream cheese and sour cream until smooth.
Stir in the diced green chilies, taco seasoning, 1 cup of the shredded cheese, and the shredded chicken. Mix gently but thoroughly.
Pour ½ cup of enchilada sauce into the bottom of the prepared baking dish.
Place approximately ⅓ cup of the chicken mixture down the center of each tortilla. Roll each tortilla tightly and place seam-side down in the baking dish.
Pour the remaining enchilada sauce over the rolled tortillas, ensuring they're completely covered to prevent drying out.
Sprinkle the remaining 1 cup of cheese evenly over the top.
Bake uncovered for 20-25 minutes, until the cheese is melted and bubbly and the edges begin to turn golden brown.
Let stand for 5 minutes before serving. Garnish with chopped fresh cilantro.
