Onions peel, halve and in strips cut. Cut meat into large cubes. Heat the oil in a roasting pan and fry the meat in it while turning. Finally add the onions, fry briefly and season with celery salt and pepper.
Pour about 750 ml of water on it, so that the meat is just covered. Add caraway and ##clove##, bring to the boil, cover and stew for about 1 1/2 hours. Peel the cucumber, cut it in half lengthwise and remove the seeds.
Cut the cucumber into cubes. Chop bread finely. Peel and wash potatoes, cut into pieces and cook covered in little boiling salted water for about 20 minutes. Add cucumber and bread to the finished meat and braise for another 5-10 minutes.
Stir from time to time. Wash parsley, shake dry and chop. Stir ##mustard## into the meat sauce and season with salt and pepper. Drain potato and let it evaporate.
Arrange mustard meat with potatoes on plates. Sprinkle with parsley. Serve with salad.
