Unroll the crescent dough and separate into 8 triangles. Place in ungreased 9x13 baking dish. Press over bottom and up sides to form crust. Press the seams together and press the edges up the sides if excess.
In a large skillet, cook beef over medium heat 8 to 10 minutes, stirring occasionally, until cooked through. Drain any excess grease. Stir in salsa, taco seasoning, and green chiles, if using. Simmer 5 minutes. Spoon evenly over crust. Top with cheese.
Bake 20 to 25 minutes, or until crust is deep golden brown and cheese is melted. Let cool a few minutes before serving with your favorite toppings.
