1. In a medium-sized saucepan, bring the chicken broth to boiling.
2. Add in couscous; remove from heat, cover and set aside for about 10 minutes or until all the liquid is absorbed.
3. Meanwhile in a skillet heat oil over medium heat.
4. Add in zucchini, green and red bell peppers, onion and garlic; cook stirring until veggies are crisp-tender, about 4-5 minutes (don't over cook the veggies!).
5. Stir in the chickpeas, tomato and olives; stir until just heated through.
6. Transfer the couscous mixture to a large bowl and fluff with a fork.
7. Add in the veggie mixture with the lemon juice, salt and pepper to the couscous mixture and toss well to combine.
8. Cover the bowl and refrigerate for minimum of 2 hours or more.
