Slice the potatoes lengthwise into 1/4 inch thick pieces. Pour oil into shallow baking dish. Place the potato slices in the oil, turning to coat both sides. Crush the spices over the potatoes, turning them to coat thoroughly. Be liberal with the herbs, as most will fall off during cooking.

Let the potatoes sit form anywhere from 15 minutes to 1 hour before grilling. Add salt to taste just before grilling. Cook potatoes close to the coals when the coals are bright and glowing red. Grill one side for 3 to 5 minutes, turn, and grill other side until the potatoes are browned on the outside but soft in the middle. Serve hot.
