Preheat the oven to 375 F.
Lightly brush the dish with oil (this will prevent the tortillas from sticking).
Spread 1/2 cup of the sauce on the base of the baking dish.
Take a tortilla, lay it flat and spoon 2-3 tablespoons of the chicken mixture at one end. Then roll it up to form a log. Place it in the baking dish SEAM SIDE DOWN.
Do this for all the tortillas making sure to lay them in the baking dish side by side.
Drizzle the sauce all over the packed rows of tortillas.
Then spread 1- 1 1/2 cup cheese as the final layer.
Bake in the oven for 20 minutes.
Remove and let it cool for 5 minutes before serving.
