Place the first 4 ingredients in a bowl, zipper bag or pyrex dish and whisk to combine.
Add the chicken breasts, cover and marinade for 1 hour or overnight (I’ve done everything from marinading it for 30 minutes and up to 20 hours and it was delicious every time).
Preheat gas or charcoal grill to medium high heat.
Cook chicken breasts for 4-5 minutes on each side or until cooked through, but still moist.
