Cook couscous according to package directions. In a large bowl, combine all vegetables and couscous. In a separate bowl, mix the sauce ingredients together very well. Pour over vegetable mix and toss well. Chill 1-2 hours. Serve.
Notes
This salad is great with grilled chicken or shrimp! You can also do a light sprinkle of grated parmesan cheese or chunks of Feta cheese.
