In a bowl, stir together oil, lemon juice, apple cider vinegar, garlic, no-salt seasoning, parsley, pink salt and pepper.
Pierce chicken breasts with a fork all over. Place in a large glass storage dish. Pour marinade over chicken.
Let marinate for at least 30 minutes - 5+ hours is ideal.
Preheat the grill to medium heat. Brush grill with oil to prevent sticking.
Place chicken on the grill. Cook for approximately 5 - 6 minutes per side, depending on the thickness of chicken. The internal temperature of the chicken should reach 165degrees. Do not over cook!
Remove chicken from the grill and let rest for 5 minutes.
