Press the sausage meat as dumplings from the skin directly into boiling salt water. Cook for about 4 minutes and then drain.
Onions peel and roughly chop. Wash turkey breast and pork loin, dab dry and cut into cubes. Goulash may be diced slightly smaller. Drain mushrooms. Dissolve stock in ½ l hot water.
Mix all the meat, dumplings, onions, shish kebab sauce, ketchup, cream and stock in a roaster or in a large ovenproof pot. Season with pepper and a little salt. Cover and braise in a preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for approx. 2 ½ hours.
Remove the lid after approx. 1 ½ hours. Season the pound casserole to taste again. Serve with sour cream and baguette.
