Season with your favorite BBQ rub.
Season with your favorite BBQ rub, I chose this Texas Rub. Grill the steak to your desired temperature and then let it rest for 5-10 minutes before cutting into the steak.
Place it back in the dish after the first cooking or grilling it and before flipping it and put it back on the grill. Let it sit down in the marinade for about 30 seconds to soak up more of the flavor.
