Wash the potatoes, cover and cook in water for about 15 minutes until just cooked. Wash oregano, shake dry and chop. Clean, wash and quarter the savoy cabbage and remove the stalk. Cut cabbage into wide strips.
Peel and finely chop the onion.
Dab meat dry. Fry in hot oil for 4-6 minutes. Season with salt and pepper and remove. Heat 2 tablespoons of butter in hot frying fat. Sauté the onion until transparent. Steam the cabbage for about 5 minutes until it gets a little softer.
Season to taste with oregano, salt, pepper and nutmeg. Drain and rinse the potatoes. Grate Gouda and Parmesan cheese.
Cut mozzarella into 12 thin slices. Cut meat into 12 medallions, cover each with 1 slice of mozzarella and wrap each with 1 slice of bacon. Peel potatoes, possibly halve them.
Mix cabbage and potatoes in a large greased casserole dish. Add the meat. Mix cream and parmesan, season and pour over. Sprinkle with Gouda. Bake in a preheated oven (electric cooker: 200°C/circulating air: 175°C/gas: level 3) for approx. 30 minutes.
