In a shallow dish, combine soy sauce, Worcestershire sauce, garlic, lemon juice, pepper and oil. Add pork chops, and turn to coat evenly. Cover, and refrigerate for at least 1 hour.
Preheat oven to 190 C / Gas mark 5.
Place marinated pork chops in a roasting tin, and bake in preheated oven for 35 to 40 minutes, basting meat often with marinade. If using other meat or pork steaks use the cooking instructions on the packet.
