Cooking: 30-40 minutes (approx.)
Preheat the oven to 375°F (190°C).
In the same skillet, add more oil if needed and cook the zucchini, bell peppers, and onion until tender. Add the garlic and cook for another minute.
In a large baking dish, combine the eggplant, sautéed vegetables, and tomatoes. Season with thyme, oregano, salt, and pepper. Drizzle with remaining olive oil.
