Brown hamburger and onion.
Combine cooked ingredients in a large mixing bowl. Season with salt and pepper to taste (go heavy on the pepper). For the bottom crust, place one package crescent rolls in the bottom of a lightly greased 9x13" dish. Add cabbage and meat mixture. Then place the second package of crescent rolls on top of the meat mixture, forming a top crust. Bake at 350° for 40 minutes, cover with foil for the last 10 minutes.
