Preheat oven to 350°F. Spread bread cubes in a single layer on a baking sheet. Bake for 10 minutes.
Meanwhile, in a blender combine remaining ingredients. Cover and blend until mixture is smooth.
Transfer the hot bread cubes to a large bowl. Spoon mixture over bread cubes; toss to coat evenly with herb mixture. Return the bread cubes to the baking sheet and bake 13 to 15 minutes more or until crisp and golden around the edges, stirring once halfway through baking.
