Kosher or sea salt and freshly ground black pepper
Heat grill to medium high. Lightly oil the grates and then let them heat up.
Season steaks on both sides with salt and pepper. Place steaks on grill and let cook about 3 minutes per side (for rare).
Grill temperatures vary, but in general, a 1-inch thick steak will take about 3 minutes per side for rare (140 degrees). Add about 1 minute per side per half inch of steak and another minute per side for desired doneness (rare, medium rare, medium, medium well, and well).
