Shape 1/3 of a cup of the meat mixture into a log shape and place in the center of a cabbage leaf. Roll the cabbage leaf around the meat mixture. Repeat with remaining meat and cabbage leaves.
Preheat the oven to 350 degrees F.
Coat a 9″x13″ pan with cooking spray. Place 1/2 of the tomato sauce in the bottom of the baking dish. Place the cabbage rolls, seam side down, in the dish. Top with remaining sauce.
Cover with foil. Bake for 60-90 minutes or until cabbage is tender and meat is cooked through.
Sprinkle with remaining 2 tablespoons of parsley, then serve.
