For Aussie Lamb
Lightly brush the meat side of the lamb with Dijon mustard. Season thoroughly with the Southwest Lamb Seasoning and let stand for 15 minutes before placing on the smoker. Cover the bones with foil to prevent burning.
Smoke until the internal temperature reaches 110°F. Remove from the smoker (or the cool side of the grill) and transfer to the hot side of the grill.
Grill until the internal temperature reaches 130°F for medium rare. When the lamb is about 5°F below your desired doneness, brush with the BBQ sauce.
Remove from the grill, loosely cover with foil, and rest for 5 minutes before slicing. Serve with additional BBQ sauce.
