Soak rolls in cold water. Clean and wash the cabbage and cut out the stalk in a wedge shape. Put the cabbage head briefly in plenty of boiling water, lift it out and remove the outer 16 leaves. (Use the rest of the cabbage for other purposes.)
Cut the cabbage ribs flat and blanch the cabbage leaves in boiling water in 2 portions for 1-2 minutes. Remove with a skimmer and drain well.
For the minced meat filling, peel and chop the onion. Squeeze the bread roll. Knead minced meat, eggs, 1 1/2-2 teaspoons salt, pepper, mustard, bread roll and paprika. Put two cabbage leaves on top of each other. Divide the minced mass into eight parts. Form 8 longish meatballs.
Place one meatball on each cabbage leaf, wrap into a roulade and tie together with kitchen twine. Heat the oil in a roasting pan and fry the cabbage roulades thoroughly while turning. Add tomato paste and sauté.
Deglaze with broth, bring to the boil and braise over medium heat for about 45 minutes. Then lift out the cabbage rolls and keep warm. Bring liquid to the boil, stir in sauce thickener, bring to the boil. Season sauce to taste with salt, pepper and sugar and serve with the roulades.
