Thaw one roll of fillo following thawing instructions on package.

Preheat oven to 350°F. Unroll and cover the sheets with plastic wrap and a damp towel to prevent drying out.

In a small mixing bowl, combine the bread crumbs, bacon, and Parmesan cheese.

Place one sheet of fillo on work surface and lightly coat ½ of the sheet with cooking spray lengthwise. Fold sheet in half lengthwise and spray top layer.

Place 3 spears of asparagus on top of the fillo dough 1-inch from the short end. Sprinkle 1 tablespoon of the bread crumb mixture evenly on the asparagus.

Roll the fillo around the asparagus to create a bundle. Place bundle on a baking tray seam side down. Lightly spray the outside. Sprinkle with bread crumb mixture to garnish.

Repeat with remaining sheets of fillo dough and asparagus.

Bake for 15-18 minutes or until the fillo is a light golden brown and asparagus in tender. Serve immediately.
