Taco Bake

1 tube crescent rolls
2 c. crushed Doritos, divided
1 1/2 lb. ground beef
1 (15 oz) can tomato sauce
2 Tbsp. taco sauce
1 envelope taco seasoning
1 1/2 c. sour cream
Sliced black olives
1 1/2-2 c. shredded Cheddar cheese

Seal perforations in rolls and press into a 9×13” pan, going about 1” up sides. Sprinkle with 1 cup of chips. Cook beef until no longer pink; add sauces and taco seasoning. Simmer 5 minutes. Spoon over chips. Top with sour cream, olives, cheese and remaining chips. Bake at 350° for 25-30 minutes, until crust is lightly browned and cheese is bubbling.
