Trim any visible fat from pork. Sprinkle the pork with seasoning blend and 1/4 teaspoon salt. For a charcoal grill, arrange medium coals on one side of the grill. Place a drip pan on the other side of the grill. Place the pork on the greased grill rack over the drip pan. Cover and grill for 25 to 30 minutes or until a thermometer inserted in center of the pork registers 145 degrees F. Meanwhile, place peach halves, pitted sides down, on the greased grill rack directly over the coals. Cover and grill for about 6 minutes or until tender and lightly browned, turning once. (For a gas grill, preheat grill. Reduce heat to medium. Adjust for indirect cooking. Place the meat on greased grill rack over the burner that is off. Place the peaches on greased grill rack over the burner that is on. Grill as above.) Remove the pork from the grill; tent with foil and let stand for 3 minutes. Very thinly slice the pork.
