Preheat oven to 400 degrees. In a large skillet fry the ground beef until no longer pink. Drain and return to the pan. Add the taco seasoning mix, water and olives. Simmer 5 minutes.

Separate the crescent dough into triangles, press out slightly and place in a 9″ pie dish, points toward the center of the dish. Press seams together to seal, forming the crust.

Sprinkle 1 cup of the crushed corn chips onto the crust. Spoon meat mix over the top of the corn chips, spreading evenly.
Stir sour cream until smooth, then spread over meat. Cover with the shredded cheese and the remaining 1 cup crushed corn chips.
Bake until the crust is golden brown, about 20-25 minutes.
Serve with salsa.
