Peel the onions and cut into thin rings. Blanch in boiling water for 3 minutes. Then drain well. Mix with the diced peppers.
Mix vinegar and oil with the spices to a dressing and dress the onion salad.
Cut the Allgäuer Emmentaler into thin slices. Arrange Emmentaler, ham, Lolo Rosso and onion salad on the plates.
Shortly before serving, grind with pepper, possibly dust with some noble sweet paprika and sprinkle with parsley.
