Creating your favorite veggie pizza is simple when you follow these easy steps:

1. Preheat Oven: Preheat your oven to 475°F (245°C).
2. Prepare Dough: Roll out the pre-made pizza dough on a floured surface to your desired thickness.
3. Add Sauce: Transfer the rolled dough to a pizza stone or baking sheet. Spread the pizza sauce evenly over the surface.
4. Layer Cheese: Sprinkle the shredded mozzarella cheese over the sauce, ensuring it covers the entire pizza.
5. Add Vegetables: Begin layering your sliced bell peppers, red onions, black olives, spinach leaves, and mushrooms evenly across the cheese.
6. Season: Sprinkle dried oregano, garlic powder, salt, and pepper over the veggies for added flavor.
7. Drizzle Olive Oil: Lightly drizzle olive oil over the top of the pizza to enhance flavor and help with browning.
8. Bake Pizza: Place the pizza in the preheated oven and bake for 15-20 minutes, or until the crust is golden brown and the cheese is bubbly.
9. Check Doneness: Keep an eye on the pizza towards the end of the baking time to prevent overcooking.
10. Slice and Serve: Once done, remove the pizza from the oven, let it cool for a few minutes, then slice and serve.
