Step 1

Cook quinoa in a large pan of boiling water for 12 minutes or until tender. Drain.

Step 2

Meanwhile, rub lamb with mustard, thyme, salt and pepper. Heat a large lightly oiled non-stick pan on medium-high heat. Cook lamb for 3 minutes each side for medium-rare or to your liking. Remove from heat and rest, covered, for 5 minutes.

Step 3

Toss quinoa with remaining ingredients and season. Thickly slice lamb and serve on quinoa with lemon and harissa.
