Preheat oven to 425 degrees. Coat a 12-inch pizza pan with cooking spray. Press dough onto pan.
Spread Alfredo sauce over dough, leaving a half-inch border. Sprinkle with 1/2 cup cheese. Top with spinach, tomatoes, and bacon; sprinkle with remaining 1/2 cup cheese.
Bake until heated through and cheese is melted and lightly browned, 15-18 minutes.
