Ivan, all you have to do is peel the very dark green leaves of the cabbage off and cut off the bottom end like you would an onion. Then carefully peel the big outer light/white green ones off. You need to par boil them (in salted water) for a few min so you can roll them without them breaking on you. After taking them out of the boiling water, drop them in some ice water to stop the cooking. Then just add your stuffed pepper filling, roll up and secure with thread or tooth picks. Bake or fry. Mom always used thread, PITA to me. She did that cause she fried them, and they were not served with tomato sauce or rice inside. Mom is German so she made them her way. I loved them, as I'm not a tomato sauce or a rice guy. HTH
