Preheat the oven to 400°F.
Using a small paring knife, cut a small slit across the length of each date.
Cut the cheese into approximately ½-inch-by-¼-inch rectangles (the cheese will not cut into perfect shapes, but that's OK).
Insert a piece of Parmigiano into each date.
Lay the strips of bacon out on a work space, next to each other. One by one, place each date at the end of a strip of bacon, and then carefully roll the date along the bacon strip, wrapping it tightly.
Place the bacon-wrapped dates on a roasting rack set in a baking sheet, and roast for 10 to 15 minutes, until golden brown and crispy on the outside.
Arrange the dates in a bowl with the parsley leaves.
Remember to warn your guests that the dates are hot!
