Mackerel Couscous Salad is a refreshing and nutritious dish that combines the flavors of mackerel, couscous, and a variety of vegetables. The salad is made by mixing cooked couscous with flaked mackerel, diced cucumber, cherry tomatoes, red onion, and fresh herbs. A simple dressing of lemon juice, olive oil, salt, and pepper adds a tangy and zesty flavor to the salad. This dish is perfect for a light lunch or as a side dish for a barbecue or picnic.
