Preheat the oven to 375°F / 190°C.
Roll out the pizza dough and cut it in half.
Transfer each half to a 12-inch round baking tray.
Spread half of the pizza sauce (about 3/4 cup / 960 ml per pizza) evenly over each crust.
Arrange the veggie pepperoni slices on top of the sauce, followed by the sliced red pepper, mushrooms, onion, and olives.
Spread the remaining pizza sauce evenly over the toppings.
Sprinkle generously with non-dairy cheese.
For an extra crispy crust, drizzle a thin line of extra-virgin olive oil around the edge of each pizza.
Bake for 10 to 12 minutes, or until the crust is golden brown and the cheese is melted and bubbly.
Spread a layer of sauce over the veggie pepperoni to prevent it from drying out or curling up in the oven.
