Peel and wash the potatoes and vegetables and cut into small pieces. Peel and chop the onion. Cut meat into cubes and cooked sausages into slices. Melt butter in a large pot. Brown meat and sausage in it.
Pour on the unsoaked peas, vegetables, onion, bay leaf and 1.5 l broth and bring to the boil. Boil down for at least 3 hours while stirring until creamy. Add the remaining stock gradually, stirring again and again to prevent it from burning.
If the soup is too thick, dilute it with more broth. If it's not creamy enough, puree it gently with a hand blender. Remove laurel beforehand. Rinse parsley cold, dab dry and chop finely. Add to the soup.
Season to taste with a little salt and pepper.
Heat the wiener sausages in the soup, but do not boil them so that the sausages do not burst. Serve the pea soup with 1 sausage each.
