Raise the oven rack to the top third of the oven. Preheat to 500℉.
Make gf pizza dough, or use store-bought at room temperature.
Spread the olive oil on baking sheet. Roll out pizza dough (we use a drinking glass), and cover with plastic wrap. Let the dough rise in a warm space, while periodically working the dough to the edges of the pan under the wrap.
When the dough has expanded, remove the plastic wrap. Place in the oven and bake for 4 minutes.
Brush the crust with the fig jam. Add a sprinkle of sea salt. Place mozzarella slices, prosciutto, and fig pieces over the crust. Put the pizza back in the oven and cook for an additional 13-15 minutes. Until the cheese is bubbly and the crust is golden.
Remove the pizza from the oven. Add arugula on top. Drizzle with balsamic, sprinkle freshly grated parmigiano reggiano, and serve.
