Remove the steaks from the refrigerator 15-30 minutes before grilling to allow them to come to room temperature. Season steaks with Kosher Salt and black pepper about 15 minutes before grilling
Turn on grill to high heat and heat for about 15-20 minutes prior to cooking. If you have a temperature gauge on your grill, look for it to reach about 450-500ºF. Alternatively, you can hold your hand over the heat and you shouldn’t be able to handle it for more than about 3-4 seconds.
Place steaks on hot grill. Cover with grill lid and cook for 3-4 minutes (or more depending on the thickness of the steak). Flip steaks, cover with lid, and cook an additional 3-4 minutes. Use a thermometer to reach your desired doneness. Don't overcook! Remember carryover cooking!
Transfer to a cutting board, cover with foil, and allow to rest for 5-10 minutes before cutting
As the steak rests, grill the skewered potatoes over medium-high heat, turning 2 to 3 times, until browned and cooked through, about10 minutes.
