Pat the lamb loin chops dry with a paper towel and rub both sides evenly with jerk seasoning, sea salt, and black pepper.
In a small mixing bowl, combine the diced mango, red onion, fresh cilantro, and lime juice to create the salsa; set aside to let flavors meld.
Heat the olive oil in a cast-iron skillet over medium-high heat until it begins to shimmer.
Place the lamb chops in the skillet and sear for 3-4 minutes per side until a dark, charred crust forms and the internal temperature reaches 135°F for medium-rare.
Remove the lamb from the skillet and transfer to a plate to rest for 5 minutes.
In the same skillet, add the cauliflower rice and sauté for 2-3 minutes using the residual heat and juices until just tender.
Plate the cauliflower rice, top with the charred lamb chops, and spoon the fresh mango salsa over the meat before serving.
