I usually fast roast these because I don't have time/don't think to slow roast.

1 sprinkle sugar 1 tablespoon extra-virgin olive oil 1/2 teaspoon salt 1/2 teaspoon dried basil 1/2 teaspoon dried oregano 1/4 teaspoon freshly ground black pepper 4 pounds plum tomatoes, halved lengthwise (about 16 medium) Cooking spray

How to SLOW roast: Preheat oven to 200°. Combine first 7 ingredients in a large bowl, tossing gently to coat. Arrange tomatoes, cut side up, on a baking sheet coated with cooking spray. Roast at 200° for 7 1/2 hours. To FAST roast them- preheat oven to 400° and roast for ~ 1 hour.
