In a large zip style bag or in between two layers of plastic wrap, pound the chicken to about ¾-inch thickness, with either a meat tenderizer or a wooden rolling pin.
In another large zip style bag, place all of the ingredients for marinate and squish around with your hand, from the outside of the bag. Place the flattened chicken breasts into marinate. Let marinate for about 2 to 6 hours, or even overnight.
Cook on the grill, over medium to high heat for about 3 minutes each side. Or cook in a large skillet with 2 tablespoons of olive oil and 1 tablespoon of butter. Let rest a few minutes before slicing.
