This flavorful French Ratatouille features a medley of seasonal vegetables, including zucchini, eggplant, and bell peppers, slow-roasted to enhance their natural sweetness and caramelization. It is served alongside herbed quinoa, which adds a fresh touch with notes of parsley and thyme, while the dish is elevated by a drizzle of homemade tomato sauce that brings a rich, tangy flavor to every bite.
