Spice-Rubbed Lamb Chops

Stir together thyme, cumin, coriander, paprika, and salt in a small bowl; season with pepper. Put lamb chops on a plate; rub each side with spice mixture. Let stand at least 10 minutes, or up to 1 hour.

Heat 1 teaspoon oil in a medium heavy skillet over medium-high heat until very hot. Add chops. Reduce heat to medium. Cook chops, flipping halfway though, until deeply browned, about 10 minutes total for medium-rare. Transfer each chop to a serving plate. Divide arugula between plates; drizzle with remaining teaspoon oil. Serve with cauliflower.
