Preheat oven to 350ºF. In a large bowl, combine the shredded chicken, ¼ cup enchilada sauce and a generous pinch of salt and pepper. Mix together and taste. Season with more salt and pepper as needed.
If using corn tortillas: Wrap the tortillas in a damp paper towel and heat them in the microwave for 1 minute, flipping the them halfway through until all of them are warm and pliable.
If using flour tortillas: Microwave the tortillas on a plate for 1 minute, flipping them halfway through until all of them are warm and pliable.
Assemble the enchiladas by filling each tortilla evenly with the shredded chicken mixture and 1 cup of shredded cheese. Roll the tortillas tightly to close and place in large baking dish seam side down.
Pour the remaining 1 ¾ cup enchilada sauce over the tortillas, top with the remaining 1 ½ cups shredded cheese, and bake for 20 minutes until the cheese is melted and bubbly.
Serve immediately and garnish with desired toppings.
