1Heat coals or gas grill for direct heat. Spray half of one side of four 18x12-inch sheets of heavy-duty aluminum foil with cooking spray.
2Mix barbecue sauce, honey and cumin in small bowl. Place 1 pork chop, 3 pieces corn, 1/4 cup carrots and 1/2 cup potato wedges on center of each sprayed foil sheet; sprinkle with 1/4 teaspoon salt. Spoon 3 tablespoons sauce mixture over pork and vegetables on each sheet.
3Fold foil over pork and vegetables so edges meet. Seal edges, making tight 1/2-inch fold; fold again. Allow space on sides for circulation and expansion.
4Grill packets 4 to 6 inches from medium heat 15 to 20 minutes, turning once, until pork is slightly pink in center. Place packets on plates. Cut large X across top of each packet; fold back foil.
