Clean, wash and slice the Brussels sprouts. Peel the sharon fruits, cut them into slices and quarter them. Peel and finely dice the shallots.
Heat the oil in a pan and fry the Brussels sprouts in it, add the shallots and cranberries, sauté, deglaze with the stock and sauté with the lid on for about five minutes. Only cook the Sharon fruits briefly at the end. The Brussels sprouts should still have bite.
Season with salt and pepper and serve sprinkled with the coarsely chopped walnuts.
