Preheat the Oven: Preheat your oven to 375°F (190°C).
Prepare Your Ingredients: Slice the zucchinis and eggplants into thin rounds. Dice the tomatoes into smaller pieces.
Sauté the Aromatics: In a pan, heat olive oil over medium heat. Add the finely chopped onion and garlic and sauté until they turn translucent and fragrant.
Layer the Vegetables: In a greased baking dish, layer the sliced vegetables one after the other, starting with the zucchinis, followed by eggplants, and then tomatoes.
Season: Season each layer with salt, pepper, and fresh herbs to taste.
Add Toppings: If desired, sprinkle grated cheese on top for that extra touch of deliciousness.
Bake: Cover the dish with aluminum foil and bake for about 30 minutes. After that, remove the foil and bake for an additional 15 minutes, or until the top is golden brown and bubbly.
Serve Warm: Once baked to perfection, let cool for a few minutes before serving. Enjoy your flavorful creation!
