Spinach-Artichoke Flatbread Pizzas

Directions

1. 1
   Preheat the oven to 350 F. Line 2 baking sheets with foil.
2. 2
   In a small saucepan, bring the balsamic vinegar to a boil over medium heat. Reduce the heat to medium-low and simmer until the balsamic vinegar starts to thicken and has reduced by half, 20 to 25 minutes.
3. 3
   Meanwhile, lay out the flatbreads on the prepared baking sheets and coat with cooking spray. Bake for 5 to 6 minutes. Remove from the oven but leave the oven on.
4. 4
   Spread 2 tablespoons Alfredo sauce evenly onto each flatbread. Top each with 1 cup spinach, 1/2 cup grape tomatoes, 1/4 cup artichokes, and 2 tablespoons mozzarella.
5. 5
   Return to the oven and bake until the cheese is melted, 7 to 9 minutes. Remove from the oven and drizzle the balsamic reduction evenly over each pizza.
