One of my favorite light sides consists of a vegetable mix with couscous. I prefer it chilled and with some fresh cucumber and herbs. Sometimes I add tomatoes (seeded) as well.
1 English cucumber, diced
2 medium carrots, peeled and diced
1 cup couscous, cooked
salt and pepper to taste
splash of olive oil
Mix all ingredients together and chill. Serve as a side or as a vegetarian salad.
