This colorful and healthy grilled panzanella salad is a delicious twist on the classic Italian dish that makes the most of simple, seasonal ingredients. It combines the smoky flavors of grilled summer vegetables- with juicy tomatoes, crusty bread and a zesty vinaigrette. Panzanella salad is best enjoyed after the bread has soaked up all the flavors and juices from the veggies and dressing. —Olga Kouloufakos, Lake Pleasant, Massachusetts
