Dorito Taco Bake

I found this one on Plain Chicken, it was pretty good.  It seemed more like an appetizer chip dip than a supper dish, but I made it without the crescent roll bottom because my roll of crescent rolls had gone bad, there must have been a hole in the package.

Dorito Taco Bake

1 can refrigerated crescent rolls
1 LB hamburger
1 package taco seasoning (allergy free recipe)
8 oz can tomato sauce
4 oz sour cream
1 1/2 cups shredded cheddar cheese
1 bag doritos - crushed

Brown hamburger and drain fat.  Stir in tomato sauce and taco seasoning, simmer for 5 minutes.  Unroll crescent rolls and press into the bottom of a 9x13" baking dish.  Top with hamburger mixture, then sour cream, then cheese, then doritos.  Bake at 350°  for 30 minutes.
