Cut fat and tendons off chicken and cut in half (I like to do all this with my kitchen shears instead of a knife). Place in dish or between two pieces of plastic wrap and pound flat (3/4 inch to 1 inch thick).
Mix remaining ingredients together in a bowl and then pour into bag. Shake the bag to get all the chicken covered with the marinade. Place in fridge for 30 minutes or until ready to grill.
Heat grill to medium-high heat and then place chicken on and cook 10-15 minutes on each side until cooked through and the juices run clear.
Garnish with lemon wedges to squeeze fresh juice on top.
