1 lb. ground beef
1/2 c. chopped onion
1 (8 oz.) can tomato sauce
2 tbsp. taco seasoning
1 tube crescent rolls
1-1/2 c. crushed nacho tortilla chips, divided
1 c. sour cream
1 c. Mexican blend, shredded cheese

Brown meat and onions until done, drain. Stir in tomato sauce and taco seasoning, bring to a boil, reduce heat, simmer for 5 minutes.

Separate crescent roll dough into 8 triangles. Place in a greased 9 inch pie plate with points toward the center. Press dough together to form a crust, sealing perforations. Sprinkle 1 cup chips over crust, top with meat mixture. Carefully spread sour cream over this. Sprinkle cheese and remaining chips on top.

Bake at 350°F for 20-25 minutes or until cheese melts and crust is golden.
