Combine all the marinade ingredients in a bowl.  After cleaning and drying your fish allow it to marinade for 2 - 3 hours {1 hour minimum} in the refrigerator.

Prepare your grill on high and brush the grates with some olive oil. Place your swordfish steaks on direct heat and cook for about 7 minutes per side. Steaks are done once they've reached an internal temperature of 145 degrees (I use an internal read thermometer like the thermapen to test internal temp).Once they're cooked let them rest before serving them.
