Peel and cut the vegetables into chunks
Toss in olive oil and spread in a single layer onto a sheet pan lined with parchment paper (for easier cleanup)
Sprinkle with salt, pepper and herbs
Roast in an 200 degree oven until the vegetables are tender, about 20 - 40 minutes depending on size
In the meantime, whisk together the ingredients for the vinaigrette, and make your bread cubes
For the bread cubes, use whatever fresh or day-old bread you have, but sourdough is absolutely best, and cut it into chunks. Toast it in a pan with oil and/or butter until crispy.
