This is a good recipe for showing off the curvaceous shapes of white or Thai eggplants. Globe or Asian eggplants will also work.
1. Preheat oven to 400°F.
2. Toss together eggplants, onion, bell peppers, chiles, and oil in roasting pan. Season with salt and pepper, if desired, and roast 35 minutes. Stir in garlic, and roast 5 minutes more. Stir in tomatoes, and roast 15 to 20 minutes more, stirring every 10 minutes, or until eggplants are very tender. Stir in parsley, thyme, and tarragon.
