Heat the oil in a roasting pan, fry the peeled and finely chopped onions and garlic, gradually adding the minced meat. In the meantime, clean the savoy cabbage, cut into strips, wash and drain.
Season the well-seared mince with salt and pepper. Gradually add the savoy cabbage and fry it, so that a hearty roasted aroma is created and the savoy cabbage takes on color. Deglaze with vegetable stock and stew with the lid closed for 20 minutes, stirring occasionally.
Finally add the sour cream and season with nutmeg.
