Wash and brush potatoes. If they are too big, cut in half or quarter. Put in a baking dish or in a roaster. Sprinkle with 2 tablespoons of olive oil and sea salt and turn everything in the oil.
Cook at 200 ° C top / bottom heat (convection: 180 ° C) in a preheated oven for approx. 25 to 30 minutes, turning several times.
Put the remaining ingredients in a bowl and mix together. Season with salt and pepper. Put the finished potatoes in the dressing and mix.
