Follow these simple steps to create your Ultimate Quick and Easy Chicken Enchiladas:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare Chicken Mixture: In a bowl, combine shredded chicken, cumin, chili powder, garlic powder, and season with salt and pepper. If using, add black beans and corn to the mixture.
3. Warm Tortillas: In a skillet over medium heat, lightly warm the tortillas for about 30 seconds on each side to make them pliable.
4. Assemble Enchiladas: Take one tortilla, spoon 2-3 tablespoons of the chicken mixture into the center, sprinkle with cheese, and roll it up tightly. Repeat with the remaining tortillas.
5. Arrange in Baking Dish: Place the rolled enchiladas seam-side down in a lightly greased baking dish.
6. Add Sauce: Pour enchilada sauce evenly over the top of the rolled enchiladas, ensuring they are well-coated.
7. Add Cheese: Sprinkle the remaining cheese over the enchiladas, covering them generously.
8. Bake: Place the baking dish in the preheated oven and bake for about 20-25 minutes, or until the cheese is melted and bubbly.
9. Garnish and Serve: Once baked, remove from the oven and sprinkle with chopped cilantro before serving.
