Cut bread into cubes. Arrange bread cubes in a single layer in a 15- x 10- x 1-inch jellyroll pan. Bake at 375° for 20 minutes or until golden. Remove from oven, and let cool completely.
Combine tomato and remaining 10 ingredients in a large bowl; toss well. Add toasted bread cubes to bean mixture just before serving; toss lightly. Serve immediately.
