How to make light and healthy couscous salad with a simple lemon vinaigrette, cucumber and herbs. We love this light couscous salad — it doubles as a side, can be the main event or works well topped with grilled chicken or Adam’s favorite, shrimp! With lots of texture from crisp cucumber, sweet tomatoes, crunchy nuts and raisins, this is certainly one of our favorites. You can even make it ahead of time.
