1 1/2 pounds ground beef
1/3 cup onions chopped
1/2 cup water
1 1 1/4-ounce package taco seasoning mix
1 8-ounce can refrigerated crescent dinner rolls
2 cups tortilla chips crushed
1 cup sour cream
4 ounces cheddar cheese shredded (about 1 cup)
1/2 cup taco sauce or picante sauce
Preheat oven to 375°. Place baking sheet on middle shelf of oven.
Crumble beef into a large skillet. Add onion and saute over medium heat until meat is no longer pink. Remove any excess fat. Stir in water and taco seasoning mix. Reduce heat to low, cover and simmer for 5 minutes.
Meanwhile, arrange crescent roll triangles in bottom and up sides of a 9-inch pie plate, pinching edges of triangles together to form a crust. Sprinkle with 1 cup of the crushed chips. Spread hot meat mixture evenly in crust. Spoon on sour cream, then sprinkle with cheese. Top with remaining chips.
Bake on preheated baking sheet for 25 minutes or until edge of crust is browned and cheese melted.
