Place lemon juice, honey, oil, scallions, peppers, thyme, salt, allspice and nutmeg in a blender or food processor; cover and process until smooth. Pour half into a small bowl for basting; cover and refrigerate. Pour the remaining marinade into a large resealable plastic bag and add the chicken. Seal the bag and turn to coat; marinate in the refrigerator for up to six hours.
Drain and discard marinade. Coat a grill rack with cooking spray and preheat grill. Cook chicken, covered, over medium heat until juices run clear, four to six minutes on each side, basting frequently with the reserved marinade.
