Wash the potatoes thoroughly and cook with the skin on for about 30-35 minutes.
Mix the cream cheese, Gorgonzola and egg yolks together. Wash the chives, pat dry and cut into fine rolls (with scissors or a knife). Mix into the cheese mixture and season with salt and pepper.
Drain the potatoes and let them cool down a little. Then cut in half lengthways. Hollow out the potato halves with a teaspoon or ball cutter. Mash the potato innards and stir into the cheese mixture. The mixture is now filled into the potatoes and baked at 200 degrees for about 15-20 minutes (don`t forget to preheat!)
In the meantime, clean, wash and pluck the radicchio and the iceberg lettuce (you can also cut it, but I pluck it). Mix in the marinade ingredients and pour over the salad and garnish on the plates. Then distribute 3 potato halves on each plate and garnish with parsley and chives.
