Rub the roast with olive oil and sprinkle with dry rub or steak seasoning. Preheat the grill to heat. Insert a thermopro meat thermometer (or have an instant read thermometer handy). Place roast on grill, cook on side one for 3 minutes, turn meat and grill on side two.
Lower gas to medium-low. The temperature of your grill should be between 275-325 degrees. Grill for approximately 20 minutes, baste with sauce.
Sear the roast on both sides.
Using a meat thermometer, cook the steak to your desired temperature: 140°F for medium rare, 145°F for medium. Do not overcook, this cut has very little fat and can dry out quickly
Remove the triangle steak from the grill and allow the meat to rest. Cut thin slices against the grain. Serve warm.
