Making Cheese Enchiladas with Chili Gravy is straightforward if you follow these steps:

1. Preheat the Oven: Preheat your oven to 375°F (190°C).
2. Prepare Gravy: If using homemade chili gravy, prepare it according to your recipe or warm store-bought gravy in a saucepan.
3. Sauté Onions: In a skillet, heat the olive oil over medium heat. Add the chopped onion and sauté until translucent, about 5 minutes.
4. Warm Tortillas: Quickly warm the corn tortillas in a microwave or on a skillet to make them pliable.
5. Fill Tortillas: Place a small amount of shredded cheese (about 2 tablespoons) in the center of each tortilla, followed by a spoonful of sautéed onion. Roll up the tortillas tightly.
6. Arrange in Baking Dish: Place the rolled tortillas seam-side down in a greased 9×13 inch baking dish.
7. Pour Chili Gravy: Pour the chili gravy evenly over the filled enchiladas.
8. Add More Cheese: Sprinkle any remaining cheese on top of the gravy.
9. Bake: Cover with foil and bake for 20 minutes. Remove the foil and bake for an additional 5 minutes, or until the cheese is melted and bubbly.
10. Garnish and Serve: Remove from the oven, garnish with fresh cilantro if desired, and serve hot.
