Prep: 1. Finely chop parsley and cilantro. 2. Make marinade: mix together salt, cumin, coriander, pepper, garlic, cilantro, parsley, vinegar, olive oil, and cayenne. 3. Marinate steak while grill heats (or up to a few hours) in half of the sauce (save remaining half of the marinade to serve on the side). 4. Preheat grill. Make: 1. Place the steaks on the grill and cook until golden brown and slightly charred (the blood will start to rise to the top), 4 to 5 minutes. Turn the steaks over and continue to grill 3 to 5 minutes for medium-rare (an internal temperature of 135 degrees F), 5 to 7 minutes for medium (140 degrees F) or 8 to 10 minutes for medium-well (150 degrees F). 2. Serve with remaining sauce on side.
