Preparation Steps

• In a large bowl, whisk together the flour, yeast, sugar, and salt.
• Add the warm water and olive oil. Mix until a shaggy dough forms.
• Turn the dough out onto a lightly floured surface and knead for 5-7 minutes until smooth and elastic.
• Place the dough in a lightly oiled bowl, cover with plastic wrap, and let rise in a warm place for 1 hour, or until doubled in size.
• Preheat your oven to 400°F (200°C). Line a baking sheet with parchment paper.
• Punch down the dough and roll it out on a lightly floured surface into a large rectangle, about 12x16 inches.
• Spread the pizza sauce evenly over the dough, leaving a 1-inch border.
• Sprinkle the mozzarella cheese over the sauce, then add your desired fillings (pepperoni, sausage, mushrooms, bell peppers, etc.).
• Carefully roll up the dough from the long side, pinching the seams to seal.
• Place the stromboli, seam-side down, on the prepared baking sheet.
• In a small bowl, whisk together the egg and water for the egg wash. Brush the top of the stromboli with the egg wash.
• Bake for 20-25 minutes, or until golden brown and cooked through.
• Let cool for a few minutes before slicing and serving.
