Preheat pellet smoker to 225. Put your GrillGrates on the rack near the stack. I did these "griddle" side up, but to each their own.
Season the steak liberally with your favorite seasoning (I used Meat Church's Holy Cow - coarse peppery blend.
Place on the rack (not the GrillGrates) until internal temp is 120-130 - approx. 1 hour.
Remove steak from grill and place on cutting board, tent with aluminum foil. Crank the pellet grill to 500 or so - get it hot!
When it's going full grill mode, place the steak on the GrillGrates and bask in that sizzle.
I went 3-4 minutes each side until your IT hits your mark. See Notes for the "doneness" scale
Remove when you've hit that temp, rest for 5-10 minutes - let those juices come back.
Slice and Eat!
