What's good about this salad is that you can use day-old bread, even stale bread, if necessary. You see, the bread is toasted in the oven before mixing with the other ingredients. That means the bread doesn't get squishy like croutons, and its crunchy taste prevails. The recipe given below is a basic panzanella. And the great thing about this is that you can add any other vegetables you desire: blanched peas, green beans, fava beans, mushrooms, broccoli, etc. You can even add pieces of ham, salami, or cooked chicken to it. The possibilities are endless.
Salt and ground black pepper to taste. Preheat oven to 375 degrees. Spread bread out on a baking sheet or pan and bake until golden, about 14 minutes, flipping once halfway. Then let cool.
In a large bowl, toss together the bread pieces, tomatoes, zucchini, onion, garlic, mint, basil, dill, and parsley. In a small bowl, mix olive oil, vinegar, salt and pepper. Pour over bread salad. Toss. Adjust seasonings, if necessary; and let stand for at least one hour for flavors to blend before serving.
