Mix the minced meat with the egg, the squeezed bun, the onion and the garlic and season with mustard, salt and pepper. Finely slice the cabbage.
Line the bottom of a saucepan with half of the herb and put the meat dough on top. Cover with the remaining cabbage, season with caraway seeds to taste and top up with the stock. Bring to the boil and simmer covered for about 30 minutes on a low heat.
