For the marinade: Combine all of the marinade ingredients in a shallow baking dish large enough to hold the pork slices in one layer. Thoroughly coat the pork with the marinade and marinate for at least 2 hours.
Meanwhile start a fire. Grill the meat over hot coals or wood embers for about 3 minutes on each side, basting with the marinade.
This recipe serves 4.
Variation with Broiled Pork Loin Slices: Prepare in the same way and cook 3 minutes each side under a hot broiler.
