In a skillet over medium heat add 1 tablespoon of olive oil. When oil is hot saute carrots, onion, and celery for 4 minutes. Remove mixture and set aside.
Add potatoes to the skillet and brown. Turn heat to low and cover potatoes, cook for 15 minutes or until the tines of a fork can pass easily through the flesh of the potato.
Fluff couscous with a fork and add veggies, drizzle with remaining olive oil.
Add salt and pepper to taste. Top with shaved Gruyere cheese and parsley.
