1. Heat a charcoal or gas grill until hot (you should barely be able to hold your hand 3 or 4 inches from the fire), or use a grill pan or medium-sized skillet over medium-high heat.
2. Meanwhile, bring the steak to room temperature, pat it dry with a paper towel, and sprinkle both sides with salt and pepper.
3. Grill steak until nicely browned, 3 to 4 minutes per side. Move the meat to a cooler part of the grill and cook for another 5 to 7 minutes, turning once. Insert an instant-read thermometer to check for doneness; you want it to be 145 degree F to 160 degree F for medium-rare to medium. Cover and let rest for 5 minutes before cutting across the grain into thin slices.
