Preparation:

• Pie Dough:
• Mix the flour, salt and baking soda in a bowl. Blend the shortening into the flour with a fork or clean hands until a shaggy dough forms. Beat eggs and add them in. Slowly add the ice water, a little bit at a time, to the flour mixture until it's able to form a ball of dough. Cover with plastic wrap and refrigerate for at least an hour.
• Filling:
• Lightly brown the sausage in a 1 tsp olive oil, and let cool.
• Mix the sausage, meats, hard boiled eggs, ricotta, pecorino, 3 eggs, and mozzarella, and sprinkling of salt and pepper.
• Preheat the oven to 375 degrees. Remove the dough from the fridge and cut in half. Roll out each piece, slightly larger than what you're putting it in.
• Place the larger of the dough on the bottom, bringing the sides up the side of your springform pan or Pyrex dish. Fill with your meat, cheese, and egg mixture and smooth out the top. Place the second piece of dough on top, making sure to crimp the sides so no mixture falls out when baking.
• Crack one egg in a small bowl, whisk and add a tablespoon of water. Brush the whole thing with the egg wash. Place the Pizza Rustica in the oven, and cook for about an hour, or until the top is nice and golden brown. Wait for it to cool slightly before digging in! This is also delicious room temp!
