Mix all the ingredients, except the last bit of flour, in a stand mixer. If the dough is too watery, add the extra flour. Knead for 7 minutes. Transfer to an oiled bowl, cover, and let rise for 45 minutes.
Preheat the oven to 450 °F (232 °C). If you do not already have a pizza stone in the oven, put it in now.
Mix the sauce in a saucepan and cook until just hot.
Slice the onion and mushrooms.
Divide the dough into 2 balls.
You can either roll both out for two pizzas, or you can put one in the refrigerator for a couple of days.
Roll the outside so the dough looks round. Have parchment paper ready. Put the rolled out dough on the parchment paper. Use a ladle to put on the sauce and spread it evenly. Top with the onions and mushrooms and finally the cheese. Put dollops of pesto on the cheese.
Put the parchment paper on the pizza peel and gently transfer the pizza to the pizza stone. The parchment paper will allow it to slide in easily.
Bake for 20 minutes or until the crust had browned.
Notes
You can make pizza flavoring by combining oregano, garlic powder, parmesan, and a few chili flakes together. Store extra in a small jar.
