Fish is a source of good-for-you omega-3 fatty acids, and brown rice is a smart alternative to white rice. You also could serve the fish over whole wheat couscous or pasta. Harissa is a spicy Tunisian condiment that also pairs well with chicken. Our homemade version, which you can prepare a day or two ahead and refrigerate, is a bit milder than the fiery canned harissa you'd find in Middle Eastern markets. Add more chile paste if you want to turn up the heat.
