In a medium bowl, mix mac & cheese and chives to combine. In a small bowl, combine water and cornstarch to make a slurry.
Lay a wrapper out in a diamond shape with the point facing you. Brush the corner tip with the cornstarch mixture. Place a half strip of bacon on the bottom corner of the wrapper. Top with 1/3 cup mac & cheese. Roll wrapper up towards the top corner and wrap the sides in towards the center roll. Continue to wrap up towards the top, forming a tight roll. Brush the top with the cornstarch mixture and seal the roll.
Heat vegetable oil to 350 degrees, and cook rolls 4 at a time. Serve with your favorite condiments.
