In a small bowl, whisk together 0.5 tablespoons of olive oil, minced garlic, chopped rosemary, chopped thyme, sea salt, and black pepper.
Rub the herb marinade evenly over all sides of the lamb loin chops and allow them to marinate at room temperature for 15 minutes.
Preheat a grill or heavy-bottomed grill pan over medium-high heat until very hot.
Toss the trimmed asparagus and sliced red bell peppers in a bowl with the remaining 0.5 tablespoons of olive oil.
Place the lamb chops on the grill and cook for 4 to 5 minutes per side, or until they reach an internal temperature of 135°F for medium-rare.
While the lamb is cooking, place the vegetables on the grill or in a separate roasting pan, cooking until they are tender and show light char marks.
Remove the lamb chops from the heat and let them rest on a cutting board for at least 5 minutes to allow the juices to redistribute.
Drizzle the fresh lemon juice over the roasted vegetables and serve immediately alongside the rested lamb chops.
