1 lb. hamburger
Chopped onion
1/2 c. sour cream
1 can mushrooms, drained
Salt & Pepper to taste
Sliced American cheese

Brown hamburger, onion, then add mushrooms, sour cream and heat through (short time). Spread crescent rolls on bottom of a 9"x13" pan (like pizza crust). Seal the seams. Spread hamburger on crust, then top it entirely with the cheese. Bake at 375 degrees for 20 to 25 minutes.
