Here is how you can make them. Divide pizza dough into 8 pieces. Roll out into round disks (approximately 8 inches) for calzones or into a 12x16 inch rectangle for stromboli. For calzones, divide pizza dough into 8 pieces; roll out each piece into an 8-inch circle. For stromboli, roll out the dough into a 12x16-inch rectangle.
For calzones, add filling to the center of the dough; resist the temptation to overfill. Fold the dough over. Press and twist edges to seal. Place on a baking sheet.
