This dish can easily be made into a vegetarian dish. Just substitute the meat with one pound of shredded cabbage. Saute the cabbage in vegetable oil with a little bit of water (about 1/3cup). Cover and make it cook on a small flame for about 15min, until it is soft. Uncover and let cook until the water completely evaporates. Season with salt and pepper and mix with onions, mushrooms and bread crumbs.
