This is an excellent way to cook lamb. Even friends of ours who've never before liked lamb love this. When feeding children who turn their noses up at lamb we call this steak and they gobble it up. We do eventually tell them they really do like lamb because they just ate it! LOL, love doing that! The measurements are all approximate, use more olive oil if you wish, or more parsley, even sub out oregano for the rosemary. Double the paste recipe if using a large leg. Delicious with wild mushroom risotto and a Greek salad.
