For this delicious leg of lamb roast recipe, I used the rotisserie on a kamado grill. I start by showing you how to make a seasoning paste for the lamb roast that is full of Greek flavors, then we put the lamb on the spit rod and let it roast in front of the charcoal for a great outer sear and a tender juicy inside! This is a great recipe for your next party or family dinner!
