Preheat your oven to 400°F (200°C) and line a small baking sheet with parchment paper.
Trim any excess fat from the lamb loin chops and pat them completely dry with a paper towel.
In a small bowl, combine the minced garlic, dried rosemary, dried thyme, sea salt, and black pepper.
Rub the herb mixture evenly onto both sides of the lamb chops, pressing firmly so the crust adheres.
Toss the asparagus spears with 0.5 tsp of olive oil and a pinch of salt, then spread them on the baking sheet and roast for 12 minutes.
Heat the remaining 0.5 tsp of olive oil in a cast-iron skillet over medium-high heat until shimmering.
Place the lamb chops in the skillet and sear for 3-4 minutes per side for medium-rare, or until a golden crust has formed.
While the lamb rests for 5 minutes, steam the green peas until tender, then pulse them in a food processor with fresh mint and lemon juice until a coarse mash forms.
Plate the zesty pea mash, top with the herb-crusted lamb chops, and serve alongside the roasted asparagus.
