How to Make It
Preheat the oven to 450°. In a small bowl, combine the honey, mustard and 2 tablespoons of the olive oil. Arrange the chicken on 2 large baking sheets and coat with the honey mustard. Season with salt and pepper. Bake for 20 minutes; remove from oven. Baste with the juices and cover with foil.
In 2 large heatproof bowls, pour the boiling water over the couscous. Cover and let stand for 15 minutes. Transfer the couscous to a work surface and use 2 large forks to break it up; let cool. Gently rub the couscous into separate grains.
In a small bowl, combine the remaining 3/4 cup of olive oil with the lemon juice, lemon zest, 2 tablespoons of salt and 2 teaspoons of pepper. Return the couscous to the bowls and toss with the dressing. Add the remaining ingredients; toss well. Slice the chicken crosswise 1/2 inch thick. Serve the couscous on platters, topped with the chicken.
