For the kohlrabi vegetables with meat patties, first prepare the meat patties: Mince the smoked meat or cut it into very small pieces. Separate the egg. Cut pasta dough into circles or squares and brush with beaten egg white. Put the minced pork as filling and form pasta dumplings. Place the pastries on a board and cover with a tea towel.
For the kohlrabi vegetables, peel the kohlrabi, peel the potatoes, cut both into bite-sized pieces. Cook in a little salted water until al dente. Drain and put on salted water for the pasta pockets. Until it starts to boil, make a roux with butter and flour, pour in soup and then stir in sour cream. Add potatoes and kohlrabi, sprinkle with chives.
Cook the meat pouches in boiling salted water for about 3 minutes. Drain and serve the meat pouches with the kohlrabi vegetables.
