Fennel lends a sweet, aniselike flavor to these pork chops. To prepare fennel for cooking, remove the green stems and leaves; if desired, reserve them to flavor or garnish other dishes. Discard the outer layer of the bulb if it is tough and cut away any discolored areas. Cut the bulb in half lengthwise and remove the base of the core if it is thick and solid. Gently separate the layers with your hands and rinse well, then slice the bulb as directed.
