Drain the sauerkraut on a sieve. Clean lamb's lettuce, wash thoroughly several times and also drain. Peel onion and cut into fine rings. Peel oranges so that the white skin is completely removed. Use a sharp knife to remove the orange fillets between the parting skins and squeeze the juice from the parting skins in a bowl. Mix yoghurt, honey, peppercorns and about 6 tablespoons of orange juice and season the sauce with salt and pepper.
Carefully mix the sauerkraut, onions, orange filets and yoghurt dressing, up to 4 tablespoons. Arrange the lamb's lettuce on 4 plates and arrange the sauerkraut salad on top. Roll up the slices of smoked pork and finally place them on the salad. Add the rest of the sauce as a blob. Garnish with orange slices as desired. Serve immediately
