Drop all of the Steak Seasoning ingredients into an empty pepper mill and shake for them to blend. Generously grind about 1 tbsp of steak seasoning on each side of the porterhouse steak, then let rest for 45 min at room temperature;
In the preheated grill: Place a cast iron skillet over direct heat and mix all of the Hickory Brown Sugar Beans ingredients together except the beans. Simmer for 5 minutes then add the beans and place the skillet in indirect. Add hickory wood chunks onto hot coals and close the lid for 30 minutes;
Grill the porterhouse steak over direct heat for 4 to 6 minutes per side or until desired doneness. Close the lid if there are too many flare ups;
Let the steak rest for 10 minutes, then separate the tenderloin and strip from the bone. A steak that thickness should easily serve two.
