Add the sausage to a skillet over medium heat, using a spatula to crumble it until fully cooked.
8 ounces ground Italian sausage
Add the sausage to a mixing bowl.
Use a sharp knife to cut the pepperoni into smaller pieces. This is optional, but I like that it helps distribute the pepperoni throughout the Hot Pocket better.
3 ounces sliced pepperoni
Add the pepperoni, cheese and pizza sauce to the bowl with the sausage and mix well.
1/2 cup pizza sauce, 2 cups shredded mozzarella cheese
Place the bread dough onto a clean surface and roll it into a large rectangle (about 15 inches by 12 inches).
1 pound bread dough
Cut the dough into 6 even rectangles.
Divide the filling between the 6 pieces of dough.
Fold the long edges of the dough up and over the filling and pinch the two sides together; transfer to the baking sheet seam-side down; repeat with all 6 pieces of dough.
Whisk together the egg and water to create an egg wash.
1 egg, 1 tablespoon water
Brush the egg wash over the tops of the hot pockets then sprinkle with parmesan cheese and Italian seasoning.
2 tablespoons grated parmesan cheese, 1/2 teaspoon Italian seasoning
Use a sharp knife to cut a few slits into the top of the hot pocket to release steam during baking.
Bake for about 15 minutes or until golden brown.
Let cool for 5-10 minutes before enjoying.
