Preheat your oven to 220°C (430°F) and prepare your baking sheet by lining it with parchment paper.
Place the vegan dough on a lightly floured surface and roll it out evenly with a rolling pin until about 1/4 inch thick, creating a round or rectangular base.
Transfer the rolled dough onto the prepared baking sheet, then spread a thin layer of tomato sauce over the surface, leaving a small border around the edges.
Sprinkle the vegan cheese evenly over the tomato sauce, covering most of the surface for that gooey, melted effect.
Distribute the sliced roasted peppers across the pizza, followed by spoonfuls of caramelized onions for sweetness and depth.
Sprinkle chopped fresh basil over the top for a burst of herbaceous flavor, then drizzle with olive oil to help the crust crisp up and add aroma.
Bake the pizza in the oven for 12-15 minutes, or until the crust is golden and the vegan cheese is bubbling and slightly browned.
Remove the pizza from the oven and let it rest for 5 minutes to settle the toppings and avoid burns.
Slice the pizza into pieces, reveal the melty cheese and vibrant toppings, and enjoy the satisfying, colorful bites.
