AMERICAN LAMB BURGERS
Gently form the lamb into 8 burgers; make sure meat is not compressed. Season generously with salt and pepper; grill to desired doneness. Remove some of the bread from the rolls to make a better bread-to-burger ratio. Grill rolls briefly; cool. Spread both sides of rolls with mayonnaise, spoon on some of the onion relish, some arugula leaves and the cooked lamb burger.
