Place the potatoes on a baking tray lined with baking paper. Bake in the preheated oven (electric cooker: 200 °C/ convection oven: 175 °C/ gas: level 3) for 19-23 minutes. Turn the potatoes after about 14 minutes.
Wash the dill, dab dry and put 1 flag aside for garnishing. Pluck the remaining flags and cut them into small pieces. Mix cream cheese, yoghurt, vinegar, milk, honey, mustard and dill and season to taste with salt and pepper.
Chill mustard dip. Halve the peppers, clean and wash. Cut the pepper halves into pieces. Halve sausages. Heat 1 tablespoon of oil in a pan and fry the sausages briefly all around.
Take the sausages out of the pan and put them on the skewers, alternating with the pepper pieces. Heat 1 tablespoon of oil in the pan and fry the skewers over medium heat for 3-4 minutes. Wash the marjoram, dab dry and chop the leaves coarsely.
Sprinkle skewers with marjoram and pepper and serve with dip and potatoes.
