Turn out the Schichtkäse on a clean kitchen towel and let it drain. Roast the hazelnut flakes in a pan without fat and let them cool down. Clean and wash the rocket and lollo bianco and drain well.
Peel and finely chop the onion. Heat the sunflower oil in a pan and fry the diced ham lightly. Add onions, steam briefly and deglaze with vinegar. Remove from the heat. Season with pepper and a little salt and stir in olive oil.
Let it cool down a little. In the meantime, wash the basil, dab dry and cut into fine strips, except for a little garnish. Stir the basil and half the hazelnut leaves into the sauce. Cut Schichtkäse into about 12 large cubes and arrange with the salad.
Spread lukewarm sauce over it and sprinkle with remaining hazelnut leaves. Serve garnished with basil. Serve with fresh farmhouse bread.
