Though we adore the recipe these are based on (David Bonom's Aromatic Slow-Roasted Tomatoes from December 2009), we wanted a faster update. So in place of plum tomatoes went little grape tomatoes, which roast to concentrated sweetness in less than half the time. Serve as they are for a side dish, on crostini with ricotta for an appetizer, or tossed with pasta and oil for a main dish.
1. Preheat oven to 200°.
2. Combine first 7 ingredients, tossing gently to coat. Arrange tomatoes, cut sides up, on a baking sheet coated with cooking spray. Roast at 200° for 3 hours.
