Quarter the carrot lengthwise, then thinly slice. Cut the zucchini into 1cm chunks. Thinly slice the spring onion. Finely chop the coriander, including the stems. Crush or finely chop the garlic. Finely grate the zest of half the lemon*, then juice the half.
Step 2 — Prep chicken
CHICKEN OPTION Combine the garlic, lemon zest, Moroccan seasoning and 1 tbs olive oil in a shallow dish and season with salt and pepper. Thinly slice the chicken into strips. Add to the seasoning mixture and toss to coat.
Step 3 — Soak couscous
Put the couscous in a large heatproof bowl, add 1 tsp extra virgin olive oil, pour over 200ml boiling water and cover with a plate. Stand for 5 mins or until the water is absorbed. Fluff the couscous with a fork.
Step 4 — Prep coriander yoghurt
Meanwhile, combine the yoghurt and half the coriander in a bowl and season with salt and pepper.
Step 5 — Finish couscous
