This is sooooooooooo good i can't even explain it!!!....and SIMPLE!!
1 leg of lamb, 4 to 5 pounds, boned and butterflied
1 large bottle of Italian salad dressing (you can make your own but WHY bother)
Buy your lamb already boned
Butterfly and remove all visible fat
Place lamb in large, zip lock plastic bag
add salad dressing and marinate all day or overnight in frig
Grill over charcoal or in gas grill until medium rare (i use meat thermometer - 180 degrees)
let meat rest and than slice ..... Enjoy!
I use the same method above for shishkabob....cut the lamb into chunks and marinate overnight;
skewer meat with chunks of peppers, onions, tomatoes and grill...
