We were recently making cheese filled breadsticks. Just get some string cheese (many suppliers will have it) I believe the last string cheese I used came from Sargento. Form the dough into thin skins, like you would for a thin crust pizza, then, using a pizza wheel, cut the dough into strips wide enough to wrap around the string cheese and about 1/2-inch longer. Roll the dough around the string cheese and seal by putting just a little water on the sealing edge. Using your fingers, press the ends closed and set on a baling sheet with the seam facing down. Brush the breadsticks with a little olive oil and allow to proof for about 20 minutes, then bake until lightly browned. Use the string cheese at refrigerated temperature, not frozen.
