Start by preheating your oven to 450-500 degrees, preferably with a pizza stone, for at least 20 minutes.
Next, prep your chopped tomatoes. Just season them with a bit of salt, pepper, and oregano, and it makes a great pizza sauce. Chopped tomatoes such as Pomi (or any canned tomato) work great.
Next, roll out your dough to the thickness that you’d like, and use a fork to poke holes in the middle of the pizza, where the sauce and toppings will sit.
When that’s done, brush a bit of olive oil over the crust and then add a layer of your chopped tomato sauce (as much or as little as you’d like). Follow that with bits of provolone, and the spinach, onion, mushroom, and garlic. It is also a good idea to lightly coat the vegetables in olive oil.
When your pizza is ready, pop it in the oven for 12-15 minutes (or 7-10 minutes for thinner crusts), or until the crust is golden, and the cheese has a nice color. The cooking time will vary based on the thickness of your crust, so it’s best to keep a close eye on it.
