Lamb is one of those meats in particular that has plenty of flavor on it's own, and it doesn't need to be doctored up with all sorts of spices and herbs like chicken does, or a bland piece of pork or beef. In fact, I hate it when restaurants put too much stuff on their lamb. One restaurant I ordered it at put panko breading on the rack of lamb - I mean, why would you take a cut of meat like that and more or less turn it into a country fried steak?
Just some salt, pepper, garlic and parsley is all I use when I cook it. For lamb chops I will either grill them or fry them in a pan with olive oil. If I have the time and the budget I love a slow roasted leg of lamb. It's important for it to develop a dark crust on the outside though because it adds a ton of flavor to it.
