How to Make It
Place the bread cubes in a single layer on a cookie sheet and toast in a 350°F oven for three to five minutes or until golden. Let cool.
Place the toasted bread, tomatoes, onion, basil and cucumber in a large mixing bowl and set aside while you make the vinaigrette.
Combine all the vinaigrette ingredients into a jar or small container and shake vigorously until thoroughly combined.
Pour half of the vinaigrette over the panzanella and toss gently but thoroughly. Add the remaining vinaigrette, toss once more and serve.
