A Provençal baked vegetable masterpiece — thin rounds of zucchini, tomato, eggplant, and yellow squash arranged in overlapping concentric layers in an oiled gratin dish, scattered with garlic, thyme, and olive oil, baked until the vegetables meld into a mosaic of deep, sweet, roasted flavors. Beautiful, seasonal, and naturally keto.
