In a medium saucepan, bring 2 cups of chicken broth or vegetable broth to a boil over medium-high heat.
Once the broth is boiling, remove the saucepan from heat. Stir in 1 1/2 cups of whole wheat couscous, cover, and let it sit for about 5 minutes.
After 5 minutes, uncover and fluff the couscous gently with a fork. Stir in the finely grated Parmesan cheese and sliced green onions.
Add fresh ground black pepper to taste, and optionally a pinch of salt.
Transfer the Whole Wheat Couscous Side Dish to a serving bowl and enjoy warm.
