Preheat oven to 375°F (190°C). Lightly grease a 9x13 inch baking dish.
In a medium bowl, combine the shredded chicken, diced green chilies (undrained), salsa verde, sour cream, cumin, salt, and pepper. Mix well until evenly combined.
Warm the corn tortillas slightly to make them pliable. You can do this by heating them in a dry skillet for about 30 seconds per side, or by wrapping them in a damp paper towel and microwaving for 30-60 seconds.
Spoon about 2 tablespoons of the chicken mixture into the center of each tortilla. Sprinkle with a little shredded cheese. Roll up the tortillas tightly and place them seam-side down in the prepared baking dish.
Pour the enchilada sauce evenly over the rolled tortillas. Sprinkle the remaining shredded cheese on top.
Bake for 20-25 minutes, or until the cheese is melted and bubbly and the sauce is heated through.
Let stand for a few minutes before serving. Garnish with your favorite optional toppings like sour cream, cilantro, or avocado.
Notes
For a spicier enchilada, add a pinch of cayenne pepper to the chicken filling.
