Pour 1 cup of couscous into a bowl. Add boiling hot water to cover, cover the bowl, and fluff with a fork every 2 minutes to prevent sticking. Let the couscous absorb the water and become tender, about 10 minutes.

Dice the vegetables and add them to the soaked couscous in a serving bowl.

Pour the dressing over the salad and gently toss to combine. Serve.
