Niçoise is typically a salad composed of tuna, tomatoes, hard-boiled eggs, Niçoise olives, and anchovies, dressed with a vinaigrette. We substituted kalamata olives for Niçoise, since they are easier to find. Serve with Goat Cheese Crostini.
Although it is one of the most popular species, tuna is tricky when it comes to sustainability. To make sure you're making a sustainable choice, check out Monterey Bay Aquarium's Seafood Watch for up-to-date information on the best tuna choices.
