Peel, wash and dice the potatoes. Heat the oil in a large pan and fry the potato cubes in it for 15 minutes until golden brown on medium heat.
In the meantime, cut the sausages into oblique slices. After the potatoes have cooked for 5 minutes, add the sausage slices and fry them with them. But then I took the sausage out again and fried it in an extra pan and added it again later.
Clean and wash the leek and cut into rings. Wash the peppers, remove the seeds and cut into pieces. Put the vegetables with the drained mushrooms in the potato pan for the last 5 minutes and fry them with them. Season everything with salt, pepper and paprika. Then deglaze with the broth and stew for another 5 minutes.
Finally add the sour cream, except for a tablespoon for garnish, and stir. Season again to taste and arrange on plates with the sausage slices. Garnish with a blob of sour cream, paprika powder, marjoram and chopped parsley as desired.
