No need to over-think this one!! You’ve got the best steak in the counter. Just season it up & place on a hot grill, 4 min on each side to sear in the juices. turn heat down to a med temp & cook 4-6 mins each side. Keep in mind you can always throw it back on the grill if it needs more cooking but you cannot reverse an over-cooked steak!! So err on the side of rare & sear that steer over high heat!!
