Preheat the oven to 375°F. Line a baking sheet with parchment paper, set aside.
Lay out the crescent roll triangles on a clean work surface.
Evenly distribute the turkey, stuffing, and cranberry sauce onto the roll, placing it on the large end of the triangle. I like to place the stuffing, then turkey on top, and end with the cranberry sauce.
Carefully roll the pointed end of the triangle over the filling and tuck it under to make a package. Place each package on the lined baking sheet about 2 inches apart.
Bake for 9-12 minutes until golden brown.
To serve: place a scoop of warmed up leftover mashed potatoes on a plate, top with two turkey bundles, and ladle some gravy on top.
