Preheat oven to 375°.
Use your hands or a rolling pill to roll dough out to your liking, then transfer it onto a large baking sheet. Drizzle it with 2 tbsp olive oil then set aside.
Next, heat 1 tbsp olive oil in a small skillet then add the onions. Cook the onions until they're translucent, then transfer them onto the pizza dough.
Next, add the shredded mozzarella, then the burrata. Place pizza in the oven and bake for 15 minutes.
Then, remove pizza and add the arugula and pistachios; bake pizza for an additional 5-8 minutes.
Take pizza out of the oven, slice and enjoy!
