In a dutch oven, cook the cabbage in boiling water for about 10 minutes or until the outer leaves are tender. Drain.
Rinse in cold water, and drain. Remove 8 large outer leaves (refrigerate the remaining cabbage in a bowl with a lid for another use). set the 8 leaves aside.
In the large saucepan, saute 1 cup of the onion in butter until tender. Add ½ tsp salt, tomatoes, brown sugar, and the garlic. Simmer this for about 15 minutes, making sure to stir occasionally.
In a large bowl combine the rice, Worcestershire sauce, ketchup, remaining onion, salt, and pepper. crumble the beef and sausage over the mixture and mix well.
Remove the thick vein from the cabbage leaves, to make the rolling easier.
Place about ½ cup of meat mixture on each of the 8 leaves. Fold in the sides. Staring at an unfolded edge, roll up the cabbage leaf to completely enclose the filling.
Place the seam side down in the skillet Top with the sauce.
Cover and cook over medium low heat for 1 hour. Add the V8 juice if desired.
Reduce the heat to low, cook about 20 minutes longer or until the cabbage rolls are heated through, and a thermometer inserted into the filing reads 160°.
