Cook the cabbage in boiling water until outer leaves pull away from head. Remove 12 large leaves from the head and set them aside for rolls. Finely chop the remaining cabbage and place it in the bottom of a 9x13 baking dish.
Overlap the cut ends of the leaf and fold in the sides. Beginning from the cut end, roll up the cabbage leaf and place it on top of the chopped cabbage in the baking dish, seam side down. Repeat with remaining leaves.
