In a food processor, blend together the garlic, rosemary, thyme, sage, and oil until a rough paste forms. Place the prime rib on a sheet pan over a wire rack and rub the prime rib generously with the her paste on all sides.
Season the prime rib with Pit Boss Chop House Steak Seasoning generously on all sides, then chill uncovered in the refrigerator overnight, or for 12 hours.
Once the prime rib has chilled for 12 hours, heat your Pit Boss Grill to 250F and grill for 2 hours or until the internal temperature of the roast reaches 110F, then increase the temperature to 400 and grill for an additional 15-30 minutes, or until the internal temperature reaches 125 - 140F.
Remove the prime rib from the grill, cover tightly in foil and allow to rest for 30 minutes. The final temperature of the prime rib should be 125 - 140F after resting. Serve and enjoy!
