easy, few dishes, good!

1 lb ground beef (shortcut- I pre-cook ground beef and keep in freezer)
8 oz sour cream
1 pk Doritos
1 pk taco seasoning
1 small onion, chopped
1 can crescent rolls
4 oz can chopped green chiles
1 pk cheese, shredded
1/2 c water

1. Brown ground beef & onion. Drain.
2. Spread unbaked crescent rolls over bottom and 1/2 up sides of 9" square (I use 8 1/2 x 11) ungreased pan, pressing with fingers.
3. Crush a layer of Doritos over the unbaked rolls.
4. Mix taco seasoning, 1/2 c water, sour cream, and chiles with the browned beef mixture. Spread over Doritos. Top with more crushed Doritos. Bake 15 minutes at 350. Top with grated cheese and bake until cheese melts. Serve with chopped lettuce and salsa.
