1Heat coals or gas grill for direct heat. Spray four 18x12-inch sheets of heavy-duty aluminum foil with cooking spray.
2Mix rice and broth in medium bowl. Let stand about 5 minutes or until most of broth is absorbed. Stir in carrots.
3Place salmon fillet on center of each foil piece. Sprinkle with lemon pepper seasoning salt and salt; top with chives. Arrange lemon slices over salmon. Spoon rice mixture around each fillet. Fold foil over salmon and rice so edges meet. Seal edges, making tight 1/2-inch fold; fold again. Allow space on sides for circulation and expansion.
4Cover and grill packets 4 to 6 inches from low heat 11 to 14 minutes or until salmon flakes easily with fork. Place packets on plates. Cut large X across top of each packet; fold back foil.
