This is a healthy alternative to traditional tabbouleh. Whole-wheat couscous is filled with fiber, keeping you feeling full.
Bring 1 cup water to a boil in a medium saucepan, and gradually stir in couscous and salt. Remove from heat; cover and let stand 5 minutes. Transfer to a medium bowl, and fluff with a fork. Stir in tomatoes and remaining ingredients. Serve immediately, or refrigerate, covered, 1 hour to allow the flavors to blend.
