Remove the outer leaves from the cabbage and cut out the stalk.
Bring water to a boil. Put the cabbage head in and boil for 10 minutes. Then take it out and peel off the leaves. Chop the inside of the cabbage.
Season the leaves with salt and pepper, top each with a slice of sausage (or with the sausage mixture) and roll up tightly.
Sauté the roulades and remaining cabbage in oil and tomato paste for about 5-10 minutes. Pour cabbage water, add vinegar and sugar and cook for 40 minutes.
Season the roulades again and sprinkle with parsley before serving.
