First cook the potatoes with their skin on, then drain, rinse and set aside to cool slightly.
During this time, remove the outer leaves from the savoy cabbage; Cut away the thick central ribs from the rest and cut the tender leaves (one on top of the other) into strips.
Put the savoy cabbage in heated butter and sauté for about 5 minutes while turning, then add almost 100 ml of water, put a lid on and cook the vegetables over a mild heat for 5 minutes; Pour into a colander to drain and set aside.
Now it's the turn of the minced meat: Fry in the heated oil until crumbly (do not brown), add the onion cubes and let them turn translucent, add tomato paste and garlic and sauté for a minute; Stir in paprika, oregano, salt and pepper, deglaze with the tomatoes, bring to the boil and cook covered for 5 minutes.
During this time, peel the potatoes and cut them into small slices that are not too thin. Grease a casserole dish with butter and smooth out half of the minced meat in it. Spread all the savoy cabbage on top, sprinkle some freshly grated nutmeg over it and place the potato slices on top. Finally, spread the rest of the minced meat over the potatoes. Sprinkle with grated cheese and bake in the preheated oven for about 25 minutes.
Bon appetit !!
