Clean the lamb`s lettuce - pinch off the roots - and wash. Divide the pomegranate and carefully remove the seeds. Be careful, the juice leaves stubborn stains. For the dressing, mix the vinegar with the mustard, salt and a little pepper, then add the oil.
Carefully mix the lamb`s lettuce with the dressing in a large bowl and serve on four plates. Scatter the pomegranate seeds on top and roughly chop the walnuts between your fingers and sprinkle them on the salad as well. Finally, use the peeler to cut the parmesan into fine slices and add to the salad.
