In a small to medium bowl whisk together the soy sauce, rice vinegar, chili oil, honey, garlic, and green onion.
Place chicken in a plastic bag or shallow dish and pour marinade over the top. Let the chicken marinade 2-3 hours or overnight.
Set grill to medium high and grill the chicken for 7-8 minutes on each side or until the chicken is cooked through and no longer pink. Internal temp will be 165 degree when done cooking.
Remove the chicken from the grill and let it sit for about 3-5 minutes before serving. This helps to seal in the juices.
Serve with salad, vegetables, or on a sandwich or wrap.
