In this very simple recipe, the spices, mint, garlic, and oil form a crust that helps seal in the lamb's juices. Sautéed carrots and roasted potatoes would be nice on the side.
Place olive oil, chopped fresh mint, minced garlic, salt, cumin, coriander, cayenne pepper, and black pepper in small bowl; mix well. Spread herb mixture over both sides of lamb chops. Transfer chops to broiler pan. Let stand 10 minutes.
Preheat broiler. Broil chops until brown and crusty, about 4 minutes per side for medium-rare. Arrange chops on platter, garnish with fresh mint sprigs, and serve.
