Preheat oven to 500 degrees. Mix all of the ingredients in a large bowl. Pour into roasting pan and place in 500-degree oven. Roast for approximately 1 hour, until the skins just start to blacken; stir the tomatoes often to avoid burning the top layer while the bottom remains undercooked. Remove from the oven and pass through a food mill with a medium disc. Bring to a boil and check seasoning. Serve and drizzle with herb oil and garlic croutons.
