Heat your grill to about 500°F. Rub the grates with a towel dipped in vegetable oil.
Season it on all sides with salt and pepper.
When the grill is ready, place the steak on the grates. Cook, undisturbed, until grill marks appear on the bottom. Flip and cook until the steak’s medium rare. (To check for doneness, use your finger to press on the meat: It should be firm around the edges but still give in the center.)
Remove it from the grill and let it rest for at least 5 minutes before serving.
