CousCous soup is so easy to make! While Bittman and others have good recipes, I usually just make it up as I go along. Some veggies, some spices, a little tomato and vegetable broth, and then through the couscous in at the last second.
In the soup above I cleaned out the crisper used carrots, celery and onion, throwing them in a Tupperwear with a chopped garlic clove, a teaspon of cumin, and half a cup of couscous. I threw everything in a saucepan at work with a little olive oil, heated it until the garlic and celery softened and cumin toasted, added a Tbs. of tomatoe paste and a cup of vegetable broth, boiled everying together for a few minutes, topped everything with a healthy dose of black pepper and had a delicious lunch.
