How to Make It
Preheat oven to 475°F. Let dough stand at room temperature 30 minutes.
Meanwhile, chop half of tomatoes, and place in a small bowl. Slice remaining tomatoes, and place in a separate small bowl. Cook sausage in a large skillet over medium-high, breaking it up with a wooden spoon, until well browned, about 7 minutes. Add chopped tomatoes, and cook, stirring occasionally, until the tomatoes release their juices and reduce slightly, about 7 minutes. Remove from heat.
Stretch dough to fit a 17- x 12-inch lightly greased rimmed baking sheet, pushing edges of dough up onto the rim. Brush oil over dough, and bake in preheated oven until the dough is lightly browned around the edges, about 8 minutes.
Remove from oven, and spread sausage-and-tomato mixture evenly over crust. Sprinkle with goat cheese and 3⁄4 cup of the mozzarella; top with sliced tomatoes, corn, and bell pepper. Sprinkle with remaining 3⁄4 cup mozzarella. Bake on middle oven rack until the cheese melts and crust is crispy, about 8 minutes. Increase oven temperature to broil, and broil 6 inches from heat until the cheese
is lightly charred, 1 to 2 minutes. Sprinkle with fresh basil.
