Preheat oven to 400ºF.
Break open the tube of dough and remove it from container. Dust your hands and lightly cover your work surface with flour or cornmeal. Roll or stretch the dough out slightly then cut it lengthwise and across to make four sections.
Spread a spoonful of cranberry sauce across one section on a diagonal.
Layer the turkey and stuffing down the middle of the dough going from one corner to the opposite corner in a diagonal line. Cover the turkey and stuffing with the cheddar. (Be careful not to overstuff the stromboli or they won't wrap up!)
Tuck the two corner edges over the filling -- you should have turkey mixture running down the middle with some filling exposed at each end.
