Wash your hands thoroughly when preparing poultry.
In a medium mixing bowl, combine all of the marinade ingredients.
Pour the marinade into a plastic self-sealing freezer storage bag (or forget the plastic and place in a glass container with a glass lid).
Add the turkey breasts and seal the bag or container shut.
Place in the refrigerator and marinate for 2 hours.
Remove the turkey breasts from the marinade and grill on direct heat for 5 - 6 minutes on each side, or until a meat thermometer registers 170 F degrees, and the turkey is no longer pink inside.
Discard the marinade.
Serve immediately while hot with your favorite side dishes!
