Cook potatoes with their skins until done. Cut the Knipp into slices, fry until crispy and then divide and fry again. Dice the bacon and the onion and also fry and pepper and salt if necessary (if the bacon is not salty enough already). Add the parsley.
In another pan, fry the eggs as fried eggs and season with salt.
Cut open the finished potatoes and fill with the bacon and onion mixture. Serve with the Knipp, the fried egg and the pickled cucumber.
