Preheat the oven to 400 degrees F.
Pour the canned tomatoes into a 3 1/2-quart baking dish and spread to cover the bottom. In a large bowl combine the remaining ingredients (excluding the bread). Toss to coat. Pour the vegetables over the canned tomatoes
in an even layer. Cover the baking dish
with foil and bake for 20 minutes. Remove the foil and bake until the edges of the vegetables are golden, about 30 to 40 minutes.
Serve alone as a side, or over toasted sourdough bread
for a main dish.
