PREHEAT oven to 400°F. Unroll dough; separate into 8 breadsticks. Cut each breadstick crosswise in half; flatten dough to 2-inch width.
SPOON 1 tsp. cheese onto centre of a ham piece. Fold ham over cheese to create a tight roll. Place ham roll near the end of each piece of breadstick dough, leaving a border. Fold dough over ham, pinching edges to seal. Repeat process for all ham pieces. Place calzones on baking sheet. Sprinkle with Parmesan cheese.
BAKE 12 to 15 min. or until golden brown. Serve warm.
