In a medium saucepan, bring the water and the 1 teaspoon oil to a boil. Stir in the couscous. Remove from heat, cover, and let stand for 2 minutes. Uncover and fluff with a fork. Add remaining ingredients and toss with dressing. Taste and add a pinch of cinnamon, if desired. Serve hot or at room temperature.
Whisk all ingredients in a small bowl and set aside.
