We are huge lamb lovers so if no one was watching, we could easily polish off that rack of lamb in one sitting. Ok, well financially that will not fly so we say that each person can have 2 or 3 ribs on the rack of lamb or 2-3 lamb lollies. Therefore, if you had 8 ribs on your herb marinated grilled rack of lamb, this would serve 3-4 people with some delicious side dishes.
