Roll the pizza dough on a piece of parchment paper into a 12×14 inch rectangle. Brush the dough with the melted butter and sprinkle garlic on top.
Sprinkle on 1/2 cup mozzarella cheese, leave a 1 to 2 inch border around 1 long edge and 2 short edges of the dough.
Top with 12 slices of ham
Place roasted peppers on top of ham.
Layer salami on top of the peppers.
Add another 1/2 cup of mozzarella.
In a small bowl, beat the egg with the water. Use a brush to coat the 3 exposed edges of your dough with egg wash.
Carefully roll up the long edge of your Stromboli, starting with the one edge that does not have the egg wash. Roll tightly so it stays together.
Seal the seam with wet fingers, then roll the stromboli so the seam is down. Seal the ends with wet fingers and tuck the extra dough on the ends under the stromboli.
Pick up the parchment paper and transfer paper and stromboli to a baking sheet. Brush with egg wash and sprinkle with the Parmesan cheese. Use a sharp knife to make a few shallow diagonal cuts into the top of the stromboli.
Bake at 375 for 25-30 minutes until the top is brown. Remove from oven and let sit for a few minutes. Slice into 8 pieces. 1 serving is 2 pieces.
