1. Preheat oven to 425°. Cut bread into 1-inch cubes (about 2 cups), and place in a single layer on a jelly-roll pan. Combine butter and garlic; drizzle over bread cubes, and toss to coat. Bake 5 to 7 minutes or until lightly toasted, stirring twice. Transfer bread to a wire rack, and cool completely (about 5 minutes).
2. Arrange salad greens and next 5 ingredients on individual serving plates. Top with bread cubes, and serve with vinaigrette.
