Next, place the American lamb loin chops into a Ziploc bag and then pour marinade over the lamb. Place the lamb in the fridge for at least 30 minutes or overnight for best results.
Preheat your grill to medium-high heat. Remove the lamb from the fridge and place on a baking sheet. Once the grill has preheated, grill the lamb about 5 minutes per side or until an internal temperature of 145 degrees is reached. Remove the lamb from the grill and allow it to rest for three minutes before slicing.
While the lamb rests, make the peach salsa. Combine all ingredients into a bowl. To serve: place lamb loin chops on a plate and top with peach salsa. Serve and enjoy.
