Cook the couscous according to package directions and immediately toss with 1 teaspoon olive oil to prevent clumping. Allow to cool.

On a large platter, arrange the arugula in a row down the center. Make a row of the cooked (yet, slightly cooled or cold) couscous next to it. Sprinkle the couscous with a little salt.

In a small bowl toss the diced tomato with the Parmesan, 1 teaspoon olive oil, balsamic vinegar, salt, and pepper. Make a row of it on the other side of the arugula.

Toast the pepitas in a toaster oven or in a small, dry pan on the stove. They are done when you start to hear a bit of popping. Toss them together with the raisins and place in another row next to the tomatoes.

Cut up the smoked salmon and place it in a row next to the couscous.
