Cut the “chain” off the side of the tenderloin. Cut off all the excess fat and “silver skin”.
Fold the tail under, about 2 1/2 inches, and truss up tenderloin using butcher twine.
Coat tenderloin with olive oil.
Dust with seasoning salt, using you hand to run in.
Coat with cracked black pepper, again using you hand to run in.
Grill over medium high direct heat for 1-2 minutes on each side, until evenly marked and charred on the outside.
Move to an indirect medium heat and grill for an additional 15 minutes, until internal temperature reaches 115 to 120 degrees, for medium rare.
Remove from grill and allow the roast to rest for 10 minutes.
Remove string and slice as needed.
Serve hot.
