Place dough on a cornmeal dusted cutting board. Allow to come to room temperature (approx. 60 minutes). Cut in half.
Preheat oven to 450 degrees.
Spray a baking sheet with non-stick spray. Spread each piece of dough out until they are your desired thickness. Place in the oven for 10 minutes.
While dough is baking, heat olive oil in a pan over medium heat. Add garlic, cherry tomatoes, sun-dried tomatoes and artichoke hearts to the pan. Sauté until cherry tomatoes begin to burst.
Add red wine vinegar, white wine, oregano, pepper and spinach to the pan and stir to combine. Once spinach is wilted remove the pan from the heat.
Remove the dough from the oven. Spread 2 oz of ricotta over each crust. Split the tomato mixture between each flatbread and spread evenly. Return the flatbreads to the oven and cook for an additional 5-7 minutes.
Remove from the oven, top with additional crumbled ricotta, slice and serve.
