An authentic Salade Niçoise, as described by Guy Gedda, Le Pape de la Cuisine Provençale, or the "Pope of Provencal Cuisine" incudes lettuce, tomatoes, eggs, green onion, anchovies, tuna, Niçois olives , artichokes, and lemon. Potatoes and green beans are not included in an authentic or traditional Salad Niçoise, however it does create for a more complete meal and tastes delicious! Use them at your own discretion :-)
