Clean, wash and chop the peppers. Heat the oil in a small roasting pan with a lid or a casserole. Sauté the paprika and sauerkraut for about 5 minutes.
Preheat oven (electric cooker: 175 °C/circulating air: 150 °C/gas: see manufacturer). Dice bread and pork loin. Fold the smoked pork, fried onions, bay leaf and juniper into the sauerkraut. Season everything with salt, pepper and nutmeg.
Spread the bread cubes over the sauerkraut mix. Dissolve stock in approx. 1 l hot water and pour cream over it. Cover and braise in the hot oven for about 45 minutes.
Grate the cheese roughly. Remove the lid, spread the cheese on the bread and bake everything open for about 15 minutes.
