Mild Cheesy Chicken Enchiladas

Step 1
Preheat the oven to 350 degrees F (175 degrees C). Lightly grease a 9×13-inch baking dish.

Step 2
Combine 3 cups Cheddar cheese and 1/4 cup sour cream in a saucepan over low heat. Cook, stirring occasionally, until melted.

Step 3
Meanwhile, mix chicken, remaining 1 cup Cheddar cheese, remaining 3/4 cup sour cream, and onion in a medium bowl until well combined.

Step 4
Arrange tortillas on a large, flat work surface. Divide chicken mixture evenly among tortillas, then roll tortillas up over the filling. Arrange in a single layer in the prepared baking dish. Pour cheese sauce over enchiladas, then top with tomatoes and olives.

Step 5
Bake in the preheated oven until hot and bubbly, 20 to 30 minutes.
