To make the calzone dough, in a large bowl, combine yeast and sugar in lukewarm water. Wait a few seconds until the yeast dissolves. Then add salt and gradually stir in flour, mix with your hands until dough is smooth. Then transfer the dough to a large cutting board sprinkled with flour. Knead the dough for about 5 minutes or until elastic. Place the dough in a large bowl coated with oil, cover with plastic wrap and let rise for 45 minutes or until the size doubles.

Preheat oven to 425°F and set aside a cooking sheet lined with parchment paper while you prepare the filling.

In a large skillet, cook sausage pieces over medium-high heat. Crumble the sausage as you stir and cook until no longer pink. Add pepperoni and vegetables. When cooked, remove from the skillet and allow to cool. Add cheese and mix.

When the dough has risen, roll it out the dough into a large rectangular shape on a lightly floured surface. Divide into 4 pieces. Spoon the meat, cheese and vegetable mixture on one side of each rectangle. Fold the dough and pinch edges to seal completely. Place them on the baking sheet and brush the surface of each calzone with egg wash. Bake for 10-12 minutes until golden brown.

Serve warm with Marinara Sauce.
