Preheat the oven to 500 degrees
Let pizza dough stand at room temperature for 30 minutes to lose its chill.
Lightly grease a half baking sheet and roll the dough to the edges.
Using the back of a large spoon, spread the tomatoes on the dough. Crumble and sprinkle oregano on the tomatoes. Arrange mozzarella evenly over the top. Top with the mushroom, olives, and pepperoni.
Slide pizza into the oven and bake 8-10 minutes. Serve immediately.
*This recipe can be doubled by rolling the dough thinner on a full baking sheet and doubling the toppings.
