In a large bowl, toss together well all of the ingredients.
To make the dressing: in a blender, puree all ingredients except oil and water until smooth. With the motor running, add the oil slowly in a stream, and then blend in the water. (This dressing keeps for one week, covered and chilled).
To make croutons: bake cubed bread in a preheated 350 degree F oven for 7 to 10 minutes or until they are crisp (they will shrink in size).
Cut sliced country style bread cut into 3/4 inch cubes.
