Salt and pepper the lamb. Using the needle and strong string, sew up the lamb into a pocket, leaving a 4 inch opening for stuffing
Prepare the stuffing: Combine all the other ingredients except the dill. If mixture is too dry, add a bit of white wine, but keep the mixture stiff.
Stuff the lamb. Sew up the pocket securely. The lamb should be in a cylinder, securely sewn up.
Liberally cover the lamb with salt, pepper and dill.
Cooking: Place on roasting rack and cook at 350F until internal temperature is 120F (this will be medium; cook 10 minutes longer if you like your lamb medium-well done)
Alternatively, cook on a rotisserie over barbecue, or in oven until desired doneness.
Serve with oven browned potatoes and a full-bodied red wine.
