Mix all ingredients except chicken in a jar fitted with a tight lid and shake vigorously. Trim chicken and flatten just a bit until same width. Grab a fork and poke holes all over breasts. Place in a baggie or shallow glass dish and pour marinade over and toss until coated. Store in fridge at-least 20 minutes, but hours is best! Grill until 165 internal temperature.
Notes
See my Greek Inspired Salad for another idea with this flavorful chicken!
