Roasted Plum Tomatoes

Preheat oven to 400 degrees. Line a baking sheet with parchment paper, and set aside. Cut tomatoes in half; remove seeds and stems, and discard. Place on baking sheet, cut side up. Drizzle with olive oil and garnish with herbs. Sprinkle with salt and pepper. Roast 5 minutes; reduce heat to 325 degrees, and continue roasting 1 hour 45 minutes. Remove from oven, and let cool. If not using immediately, store the tomatoes, tightly covered, in refrigerator up to 1 week.
