1. Put lamb into a small baking dish, rub with 2 tbsp. oil, and season with salt and pepper; set aside to let rest for 30 minutes.

2. Meanwhile, make the salsa verde: Combine mint, parsley, tarragon, capers, chile flakes, anchovies, and garlic in a medium bowl. Slowly drizzle in remaining oil while stirring with a fork to make the salsa verde; set aside.

3. Build a medium-hot fire in a charcoal grill or set gas grill to medium-high heat. (Alternatively, heat a cast-iron grill pan over medium-high heat.) Add loin chops and cook, flipping once, until browned and crusty and cooked to desired temperature, 6-8 minutes for medium rare if using loin chops (rib chops will take only 4 minutes or so to reach medium rare). Transfer lamb to a platter. Stir sauce and drizzle over chops, reserving some of the sauce to serve on the side.
