Combine Herbed Lemon-Buttermilk Dressing and chicken in a large zip-top plastic bag. Seal and marinate in refrigerator 1 hour or up to 8 hours, turning bag occasionally.
Prepare grill to medium-high heat.
Remove chicken from marinade, and discard marinade. Sprinkle the chicken evenly with salt and black pepper. Combine fresh parsley, chives, canola oil, and honey, stirring well. Spoon herb mixture evenly over tops of chicken breast halves. Place chicken, herb side down, on grill rack coated with cooking spray; grill 8 minutes each side or until done.
