In a large bowl, combine all the meats, cheeses, herbs, baking powder, and black pepper.
Crack the eggs into the bowl and mix well.
Lightly oil the sides and bottom of a 10 inch springform pan with Colavita Olive Oil
Stretch out the pizza dough into a round shape, larger than the pan, Drape the dough over the pan, pressing it into the bottom. Make sure there is enough dough to fold over the top.
Pour the filling into the pizza dough and stretch the sides of the dough over the top of the filling, pinching to close the top. Don't worry if it looks a little messy, it will bake into a nice crust.
Brush the top of the pizza dough with the egg wash.
Bake the pizza rustica in the oven for 45-60 minutes, or until a knife inserted into the center of the pie comes out clean,
Let cool slightly before serving, and enjoy!
