Preheat the oven to 475°F with a rack in the bottom position. Place a large rimmed baking sheet upside down on the rack to preheat, 8 minutes.
On a piece of parchment paper dusted with cornmeal, using a lightly floured rolling pin, roll pizza dough into a large circle, about 1?4 inch thick. Scatter it with toppings. Carefully remove the hot baking sheet from the oven and slide the parchment with the dough onto it. Bake until the dough is golden and crisp, 8 to 10 minutes. Before serving, add the remaining fresh ingredients, a ?drizzle of olive oil, and a sprinkle of sea salt.
Before her diagnosis, Caroline wrote a book on cakes called Cake Magic!. She started developing a birthday cake using her gluten-free mix found in that book. Check out other recipes she’s developing for her new life—and the stories behind them—on her blog, The Wright Recipes. Her next book, Soup Club, is a collection of recipes she made for her underground soup club of vegan and grain-free soups she delivers every week to friends throughout Seattle's rainy winter.
