Combine the first five ingredients. Stir well, then mix in the zucchini, peppers, onions, garbanzo beans, raisins and mushrooms. After vegetables are coated well, put them into a shallow baking pan. Bake for 25 minutes or until vegetables are tender. Stir occasionally.
While vegetables are baking, cook chicken breasts in a skillet using some olive oil, basil, and garlic seasoning to taste.
Cook couscous according to package directions.
When all ingredients are cooked, serve chicken and vegetables over couscous.
(Note: To decrease preparation time, cut up vegetables beforehand. I cut all mine up then froze them until I wanted to make this recipe.).
