Prep the lamb & grill. Trim any excess fat from the chops. Heat grill to medium high. Mix the cumin and salt together and split into two small dipping bowls. Rub the lamb chops with the spice mix from one of the bowls.
Grill. Place lamb chops on and cover the grill. Check every few minutes, to make sure they aren't burning. When they start browning and developing grill marks, flip them. Continue this process until all sides are browned and have nice grill marks.
Lower the heat or move the chops to a cooler section on the grill and cover again for another 4-5 minutes or until they reach desired doneness (see note).
