For ZWT 6 - Middle East. I got this recipe from the LA Times about 15 years ago. While it is pretty labor intensive compared to most cooking today, it is worth the effort. I love this dish. It is so delicious and healthy too. You can get the dried limes in any kind of middle eastern or Armenian market. They are sold with the dried spices, in larger bags. If you can't find mustard greens, use arugula (rocket). Beef can be substituted for the lamb if desired.
