In a large serving bowl, combine the uncooked couscous, diced chicken, zucchini, celery, and grated carrot.

Set aside.

In a saucepan over medium heat, bring the orange juice to a boil.

Stir the hot orange juice into the couscous mixture.

Cover the bowl tightly with plastic wrap and let it stand for 5 minutes.

After 5 minutes, remove the plastic wrap and sprinkle the mixture with chopped fresh basil, finely chopped green onions, salt, and pepper.

Gently stir the ingredients until evenly mixed.
