How to Make It
Preheat oven to 425° .
On a rimmed baking sheet, toss bread with 2 tablespoons olive oil, 1 teaspoon salt, and 1 teaspoon pepper. Bake for 10-15 minutes, or until browned and toasted. Let cool completely.
In a large bowl, combine all remaining ingredients. Add toasted bread cubes to bowl. Toss with remaining 4 tablespoons olive oil, 1 teaspoon salt, and 1 teaspoon pepper. Let stand for at least 30 minutes (and up to 4 hours) before serving. Toss with a little more olive oil, vinegar and salt if needed just before serving.
