For the Marinade
Combine marinade ingredients in mixing bowl. Dredge steaks through marinade, coating well. Marinate chilled up to 24 hours. Prior to grilling, allow to sit at room temperature for 1 hour.
For the Steak
Prepare a medium hot gas or charcoal grill. Brush grilling surface clean; oil slightly to prevent sticking. Remove cedar planks from water. Place planks on grilling surface, heating until smoke begins.
Remove steak from marinade, then season with salt and pepper. Place onto grill, cook 2.5 minutes per side or until nicely marked. Transfer steak onto plank and finish cooking for 5-7 minutes. Remove steak and allow to rest for 4-5 minutes. Reserve any juices released from the steak.
Slice steaks on bias at a 45 degree angle. Transfer to serving platter; drizzle with Honey Rosemary Sauce.
For the Honey Rosemary Sauce
Prepare vinaigrette; warm honey and rosemary in the microwave for 10-15 seconds. Whisk in cider vinegar, seasonings, any reserved cooking juice; slowly whisk in olive oil.
