Preheat oven to 400 degrees Fahrenheit.

Unroll the refrigerated breadstick dough and separate into 12 breadsticks.

Cut each breadstick crosswise in half.

Flatten each dough piece to approximately 2-inch width.

Spoon 1 teaspoon of shredded mozzarella cheese onto the center of a halved slice of honey-roasted ham.

Fold the ham piece over the cheese to create a tight roll.

Place the ham roll near the end of a flattened dough piece, leaving a small border.

Fold the dough over the ham, pinching the edges to seal and create a calzone.

Repeat the process for all remaining ham pieces and dough.

Place the prepared calzones on a baking sheet.

Sprinkle the tops of the calzones with grated Parmesan cheese.

Bake in the preheated oven for 12 to 15 minutes, or until the calzones are golden brown.

Remove from oven and serve warm.
