Add the tomato sauce to the bottom of the baking dish (remove the bay leaf) and spread evenly. Start by laying the vegetables in this order: eggplant, squash, zucchini, red bell pepper and repeat. Once it’s layered, you can press down to make sure that it is tightly packed. To finish, season the vegetables with salt, pepper, thyme (1 tbsp), and drizzle with olive oil. Cover with foil or parchment and bake for 40-55 minutes. You will know it’s ready when the tomato sauce is bubbly and the vegetables have given off their liquid. Serve hot, Bon Appetite!
