Place your choice of skirt steak, chicken, or skewers into the bowl or a zip-top bag. Pour the marinade over the meat.
Cover and marinate the meat in the refrigerator for at least 1 hour, not more than 3 hours.
Cook over flame for best flavors, grill, pan-sear, or bake until done. Brush extra marinade on as a glaze during the last few minutes of cooking for added flavor.
