Lamb leg steaks are sometimes available at my local market. I can always find either bone-in and boneless whole lamb legs, but unless I want to grill a whole leg (recipes: Grilled Butterflied Lamb Leg and Grilled Mesquite-Smoked Garlic Rosemary Lamb), lamb leg steaks can be more convenient to cook. The spice paste used to season the lamb is not hot, but spicy and flavorful. You can apply the spice paste one hour before grilling, but the lamb will taste better if left to marinate overnight in the refrigerator. If you want more heat, just add and grind dried red chili peppers to the mixture.
