Whisk blended silken tofu, olive oil, and water in a bowl of a stand mixer.
Add flour, salt, and turmeric.
Knead the dough for 5-7 minutes until smooth and elastic. Cover with plastic wrap, and let it rest in the fridge for at least 1 hour or overnight.
Prepare the Pasta & Sauce Layer:
Cook pasta al dente, undercooking around 2 minutes from the time on the package. Drain and let cool to room temperature.
In a large bowl, mix the cooked pasta, marinara sauce, and vegan sausage crumbles. Set aside.
Roast the Eggplant & Bell Peppers:
Preheat the oven to 400°F (200°C).
Toss the sliced eggplant and bell peppers with olive oil, salt, and pepper, and spread on a baking tray. Roast for 20-25 minutes until tender and slightly charred. Set aside.
Fry the Mushrooms, Onions, and Spinach:
In a pan, heat 1 tablespoon olive oil and sauté the mushrooms and onions until soft and golden.
Add the garlic, 1 teaspoon Italian seasoning, and chopped spinach, cooking until the spinach is wilted and some moisture evaporates, about 4 minutes. Season with salt and pepper. Set aside.
Assemble and Bake:
Preheat the oven to 375°F (190°C).
On a lightly floured surface, roll out the dough into a large circle, about 1/8-inch thick, ensuring it’s large enough to cover the inside of the Dutch oven with overhang.
Line the Dutch oven with the dough, pressing it into the sides and leaving the extra hanging over the edges.
Layer the filling in this order:
First Layer: ⅓ of pasta mixed with marinara sauce and sausage.
Second Layer: roasted eggplant and bell peppers.
Third Layer: vegan mozzarella cheese.
Fourth Layer: another ⅓ of pasta mixture.
Fifth Layer: spinach, mushrooms, and onions.
Sixth Layer: vegan ricotta.
Seventh Layer: the rest of the pasta mixed with marinara sauce and sausage.
Fold the overhanging dough over the top to completely enclose the filling. Make four slits to let the moisture escape while cooking.
Bake the timpano for 50-60 minutes, or until the crust is golden brown and firm.
Let it rest for 15 minutes before carefully inverting it onto a serving plate.
To serve, slice into wedges and enjoy!
Notes
Refrigerator: Cover the leftover timpano in plastic wrap or transfer it to an airtight container and store it in the fridge for up to 3 days.
Freezer: Wrap individual slices in plastic wrap and place them in a freezer-safe bag or container. Freeze for up to 2 months. Let it thaw in the refrigerator before reheating.
Reheat: Bake in a 350ºF oven for about 15 minutes, or until warmed through. Alternatively, you can reheat individual slices in the microwave for a quicker option.
