Cut the savoy cabbage into eighths, remove the stalk and the outer leaves. Peel the onion and cut into slices. Cut the bacon in half crosswise. Heat oil in a pan and fry the bacon in it. Remove and put aside.
Sauté the onion in the cooking fat and place the savoy quails on top. Pour on stock and cream and braise covered for about 15 minutes. In the meantime boil 375 ml water with 1/2 teaspoon salt. Remove the pot from the stove, add milk and fat.
Stir in the puree flakes and let them swell for about 1 minute. Season with nutmeg and stir again. Season savoy cabbage with salt and pepper. Add bacon again and warm it up. Arrange savoy cabbage with bacon-onion sauce and mashed potatoes on plates.
Garnish with parsley.
