Cut a lid off each of the peppers. Clean and wash the peppers and the lid. Put 1 olive in each pepper. Press the sausage meat mixture from the sausage skin directly into the peppers. Press on a little bit. Peel and slice the onions.
Cut the bacon in half crosswise.
Put 2 peppers with lid, onion slices and bacon on 8 wooden skewers and place them on a lightly oiled baking tray. Spread a thin layer of oil on the skewers and cook in the preheated oven (electric cooker: 200 °C/circulating air: 175 °C/gas: level 3) for approx. 25 minutes.
Stir the crème fraîche until smooth. Season with salt, pepper and cayenne pepper. Serve skewers with pepper cream. Drink: cold beer.
