Spread liver slices with mustard, sprinkle with pepper and top with ham slices. Cut cucumbers into narrow strips, place on top of ham. Roll up liver, attach with cotton thread.
Heat oil in a frying pan and brown the rolls on all sides. Warm the red wine slightly and pour it to the liver. Steam the rolls over medium heat for about 10 min (cooking time depends on the thickness of the liver slices).
Shortly before the end of the cooking time, sprinkle salt and paprika powder over the liver rolls and move the rolls heartily back and forth in the stewing stock. If necessary, add a little more red wine.
Serve with spaghetti
