Combine dry spices in small bowl. In a shallow glass dish large enough to hold chicken in a single layer, place lemon juice and oil. Add half of spice mix; stir to combine. Add chicken breasts, turning to coat both sides. Marinate 30 to 60 minutes at room temperature or 2 to 3 hours in the refrigerator, covered. Drain chicken from marinade and sprinkle both sides with remaining seasoning mix. Place breasts on hot grill with the thin ends away from the flames. Cook, turning once, until just cooked through, 3 to 8 minutes per side, depending on heat intensity and thickness of meat.
