Pat the lamb chops dry with a paper towel to ensure a proper sear.
In a small bowl, combine the minced rosemary, thyme, garlic, sea salt, and black pepper.
Press the herb mixture firmly onto both sides of the lamb chops to create a crust.
Heat the olive oil in a large cast-iron skillet over medium-high heat until shimmering.
Place the lamb chops in the skillet and sear for 3-4 minutes per side until a golden-brown crust forms and the internal temperature reaches 135°F for medium-rare.
While the lamb rests, steam the asparagus and green peas for 4-5 minutes until tender-crisp and bright green.
In a small ramekin, whisk together the finely chopped mint, lemon juice, and lemon zest.
Serve the herb-crusted lamb chops over the steamed vegetables and drizzle with the zesty mint sauce.
