Preheat the oven to 400 degrees F. Line a baking sheet with parchment.
Brush the pizza crust lightly with some oil on both sides and put on the prepared baking sheet. Top with the mozzarella, tomatoes, sausage and corn. Bake until the crust is golden and the cheese is melted, 8 to 10 minutes. Top with the scallion whites and basil, then drizzle with some oil.
