Prepare the Pie Dough: Follow the recipe instructions and divide the dough onto a lightly floured surface into two equal parts. Wrap each in plastic wrap and refrigerate for 1 hour.
Preheat your oven to 375°F (190°C).
Make the Filling: In a large mixing bowl, combine the ricotta, mozzarella or provolone, Pecorino Romano or parmesan, prosciutto, salami, ham, eggs, salt, and pepper. Mix the ingredients until well combined.
Assemble the Pie: Roll out one half and line the bottom and sides of a greased 8-inch springform pan. Spoon the filling into the pie crust. Roll out the remaining dough and place it on top of the filling. Seal the edges and crimp if desired. Brush with egg wash and cut slits on the top for venting.
Bake: Place the pie in the preheated oven and bake for about 45-55 minutes, or until the crust is golden brown and the filling is set.
Cool and Serve: Allow the pizza rustica to cool for at least 20 minutes before slicing. It's traditionally served at room temperature or slightly warm.
