Combine all the ingredients together with the exception of the steak to make the marinade. Pour the mixture into a plastic bag and add the steak. Seal and marinate this for up to 8 hours in the refrigerator.
Once the steaks have soaked up all that delicious flavor remove them from the bag and let sit at room temperature for 15-20 minutes. Fire up the grill to medium high heat. Place the skirt steaks over the heat and grill on each side for about 4-5 minutes so the steak is still pink in the middle. Remove steaks from grill and let rest for 5 minutes before slicing them at an angle.
Place all meat onto a serving dish and top with your favorite recipe for pico de gallo and serve!
