How to Make It
Heat oven to 450° F with the bottom rack set in the lowest position. Lightly oil a large rimmed baking sheet. Stretch the dough into a large oval and place on the prepared sheet; brush with 1 tablespoon of the oil.
In a large bowl, toss the sprouts, salami, and mozzarella with 1 tablespoon of the remaining oil and ½ teaspoon each salt and black pepper; scatter over the dough. Bake until the mozzarella has melted and the crust is golden brown, 12 to 15 minutes. Drizzle with 1 tablespoon of the lemon juice.
In a large bowl, toss the greens with the remaining 3 tablespoons of oil and 2 tablespoons of lemon juice and ¼ teaspoon each salt and black pepper. Serve with the pizza and red pepper, for sprinkling.
