For a spicier kick, add a pinch of cayenne pepper to the salsa verde. If you don't have rotisserie chicken, leftover grilled or roasted chicken works perfectly. Feel free to experiment with different types of cheese, such as queso fresco or cotija. For an extra layer of flavor, consider adding a thin layer of refried beans to the tortillas before adding the chicken. These enchiladas can be assembled ahead of time and baked just before serving. Add a few extra minutes to the baking time if baking from cold.
