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 ¼-inch thick. Scatter it with zucchini and Provolone, drizzle with olive oil and season with salt and pepper. 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.
Meanwhile, chop olives and transfer to a bowl with vinegar, anchovy paste, parsley and 2 tablespoons oil. Stir together to combine. Before serving pizza, drizzle with vinaigrette. Serve with side salad.
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, Catalan Food, written with chef Daniel Olivella, comes out in early September from Clarkson Potter.
