Like the vegetables, the bacon is optional and can easily be swapped out for any kind of seafood or poultry, steak or ham. Making a Niçoise salad is one of my all-time favorite things to do with leftover Roast Chicken. If you want to leave out the animal protein altogether, consider adding a cup or two of Slow-Cooked Beans, or even a handful of Ja'ala, a delicious spicy roasted nut and seed mixture. Or, crispy sautéed tofu! Truly, the possibilities are endless. Use whatever you like, or whatever you have on hand.
