Boil the potatoes until they are done, peel them and slice them lukewarm. Finely chop the onion and parsley. Cut the pickles into small cubes, the chives into rolls and chop the parsley.
Put the dressing in a salad bowl and stir in the onions, pickles, parsley and chives. Season to taste with salt and pepper. If you like, you can add some cucumber water.
Heat the oil in a coated pan and fry the bacon until crispy, then add to the dressing with the frying fat and stir everything well. Finally add the potato slices and fold in. Season again to taste.
