Preheat the oven to 350°F (175°C) and lightly spray a 9x13-inch baking dish with cooking spray.
In a mixing bowl, combine the chopped cooked chicken, softened cream cheese, southwestern or taco seasoning, and 1 cup of the shredded cheddar until well mixed.
Separate the crescent roll can into 8 triangles. Place a portion of the chicken mixture on the wide end of each triangle, then roll up tightly from the wide end toward the point.
Arrange the rolled crescents seam-side down in the prepared baking dish in a single layer.
Pour the entire can of red enchilada sauce evenly over the rolls, then sprinkle the remaining 1/2 cup shredded cheddar over the top.
Bake uncovered for 25 minutes, or until the sauce is bubbly and the cheese is melted.
Notes
Use rotisserie chicken to save time.
Soften cream cheese to make mixing easier.
Divide the cheese as directed for filling and topping.
