Heat oven to 375°F. Spray 13x9-inch (3-quart) glass baking dish with cooking spray.
Separate dough into 8 biscuits. Cut each into 8 pieces.
In a large bowl, using a spatula, mix biscuit pieces and taco meat mixture, and 1 cup of cheese, stirring gently to combine.
Spoon evenly into the baking dish.
Bake 20-25 minutes, until the biscuits are golden brown and the biscuits in the center of the casserole are baked through.
Sprinkle top with the remaining cheese and bake an addition 5 minutes until melted.
Serve with your traditional taco toppings!
