Classic Salad Niçoise originated from the French city of Nice. It traditionally consists of anchovies, tuna, and the vegetables included below. This vegetarian version offers all the delicious flavors of the original, with an extra boost of protein and fiber from the lentils. Made quickly in one pot of boiling water, this dish looks impressive but comes together in a flash. Feel free to swap in whatever vegetables are in season where you live. While not traditional, grilled zucchini or asparagus would be a delicious addition, as would come charred corn kernels or peppery fresh arugula.
