Creating Spiral Ratatouille can be straightforward if you follow these simple steps:

1. Preheat the oven to 375°F (190°C) and lightly grease a baking dish.
2. Prepare the Sauce: Spread a layer of marinara sauce evenly on the bottom of the baking dish.
3. Slice the Vegetables: Thinly slice the eggplant, zucchini, yellow squash, bell peppers, and tomatoes. Aim for uniform thickness for even cooking.
4. Arrange the Spiral: Start layering the sliced vegetables, alternating between them in a spiral pattern, so they neatly overlap.
5. Sprinkle with Herbs: In a small bowl, mix the minced garlic, chopped thyme, basil, salt, and pepper. Sprinkle this mixture evenly over the vegetable layers.
6. Drizzle Olive Oil: Generously drizzle olive oil over the arranged vegetables to keep them moist.
7. Cover the Dish: Cover the baking dish with foil to prevent drying during cooking.
8. Bake: Place the dish in the preheated oven and cook for 30 minutes covered, then remove the foil and bake for an additional 20-30 minutes until the vegetables are tender.
9. Cool: Allow the dish to cool slightly for about 10 minutes before serving so that the flavors set.
10. Serve: Cut into wedges and arrange on a plate, spooning extra marinara sauce if desired.
