Bring a large pot to boil in the meantime.
Preheat oven to 350°F
Place the cabbage head into boiling water. Cook for approximately 4-5 minutes, or until the leaves become soft.
Take 12 large leaves out of water and remove them.
Mix together the ground beef, rice and onion powder until well combined. Add the Worcestershire sauce, paprika or Italian herbs, 2 tablespoons fresh parsley, the egg, and mix in the egg.
Mix 1/2 cup of the tomato sauce in a bowl. Stir to combine.
Place each cabbage leaf on a flat surface. Then, using a small knife, cut a V-shaped hole to remove the thick portion of the cabbage rib.
Make 1/3 cup of the meat mixture, shape it into a log and place it in the middle of a cabbage leaf. The cabbage leaf should be rolled around the meat mixture. Continue with the remaining meat and cabbage leaves.
