Stretch the pizza dough to an approximately 12” circle, then brush with a thin layer of olive oil. (If you already have garlic-infused olive oil, feel free to use that instead!)
Put your 1/8 cup of apricot jam on the pizza in small dollops. Sprinkle the mozzarella cubes evenly over the dough, then add crumbles of gorgonzola. Sprinkle the walnut pieces evenly on top.
Bake the pizza until the crust is golden-brown and the cheese is bubbly, rotating once halfway through the cooking time. When it’s done, sprinkle with as much arugula as you prefer.
While the pizza bakes, stretch the next dough and assemble the next pizza. Repeat until all four pizzas are done.
