Using the two-zone cooking method, bring your grill up to heat.
When your grill is up to temp, grill the frozen steaks for around 5-7 minutes each side, checking the internal temperature as you go to ensure it doesn't rise above 90℉.
After searing the steak, season both sides with salt and pepper.
Move the steak over to the cool side of your two-zone fire, letting the indirect heat bring the interior up to 135℉ or the temperature for your preferred "doneness".
