Preheat oven to 425. Spray large baking sheet with olive oil (unless using non-stick baking sheet).
Sprinkle work surface lightly with flour. Place dough on work surface and divide evenly into 4 pieces. With lightly floured rolling pin, roll each piece of dough into an approximate 7x4 oval. Transfer ovals to prepared baking sheet. Lightly spray top of dough with olive oil cooking spray. Bake until flatbreads are golden, 12-15 minutes. Transfer flatbreads to rack to cool slightly, 2-3 minutes.
Meanwhile, combine tomatoes, vinegar, and oil in medium bowl; toss to coat. Top warm flatbreads even with tomatoes and mozzarella. Sprinkle with thyme and salt and serve.
