Place lamb leg into a large resealable plastic bag. Combine the next eight ingredients in a medium bowl. Once mixed through pour over lamb, work marinade through, seal bag and place into refrigerator.
Marinade for 4-6 hours before grilling.
Remove leg from bag and discard the marinade. Thread lamb onto spit and secure tightly. Roast over medium to medium-low coals and cook until the interior of the meat reaches (63 degrees C.), about 1 1/2 to 2 hours.
To prepare herb dressing, place all ingredients into a blender or food processor, pulse until mixed through. Remove lamb roast from grill and cover lightly with aluminium foil for 8-10 minutes.
