Directions: Combine the ingredients for the rub and sprinkle the seasoning onto the leg of lamb. Place the lamb in a shallow roasting pan and bake at 375 degrees for 45 minutes for medium rare (150F internal temperature). Remove from oven and slice thinly. For the sauce, in a small sauce pot heat the olive oil, onion, garlic, ginger, and red pepper flakes. Add the peanut butter and orange juice and bring to a simmer. Finally, stir in the coconut milk and cook until heated through. Serve as dipping sauce for the lamb.
