Remove cabbage leaves carefully, not tearing too much. Microwave cabbage for 2 minutes to make cabbage pliable. Set aside. Chop onion finely.

Put meat, onion, salt and pepper, egg, and Panko together in a large bowl, and then mix very well. Divide the meat into 10 portions and form each into a rough cylinder. Wrap each meat ball with cabbage tucking the end of the leaf under. Place cabbage wrapped meat in a pan that fits 10 pieces of them.

Add the rest of the ingredients to the pot, and cook at medium heat covering loosely for 20 minutes or so.

Serve with chopped parsley.
