How to Make It
Heat oven to 400° F. Shape the dough into 4 rounds and place on 2 cornmeal-dusted baking sheets.
Dividing evenly, top the dough with the asparagus, mushrooms, and garlic, then the ricotta, Parmesan, and 2 tablespoons of the oil. Season with ¾ teaspoon salt and ¼ teaspoon pepper. Bake, switching the pans halfway through, until the crust is golden brown and crisp, 25 to 30 minutes.
Meanwhile, in a medium bowl, toss the arugula with the lemon juice, the remaining tablespoon of oil, and ¼ teaspoon each salt and pepper. Top the pizzas with the arugula just before serving.
