Finely mince the garlic, rosemary, and thyme, then combine them in a small bowl with half of the olive oil, sea salt, and black pepper.
Rub the herb mixture evenly over all sides of the lamb loin chops and let them sit at room temperature for 15 minutes to marinate.
Preheat your grill or grill pan to medium-high heat.
Toss the asparagus with the remaining olive oil and a pinch of salt.
Place the lamb chops on the grill and cook for 3 to 4 minutes per side for medium-rare, or until they reach your desired level of doneness.
Add the asparagus to the grill alongside the lamb during the last 5 minutes of cooking, turning occasionally until tender and lightly charred.
Remove the lamb from the grill and let it rest for 5 minutes to allow the juices to redistribute.
Serve the lamb chops with the grilled asparagus and a fresh squeeze of lemon juice over the top.
