Add pasta sauce to a large skillet over medium heat.
Add in the meatballs and simmer until warmed.
Open rolls and separate into triangles. Cut each triangle in half to form two smaller triangles.
Pinch off a piece (about a 1/3rd of a slice) of mozzarella and place it onto the dough. Gently push it down to give the meatball a place to sit.
Remove a meatball from the sauce. Shake off the excess sauce and add the meatball on top of the cheese. Roll up the dough and place on an un-greased baking pan.
Continue the process until all of the meatballs are used. Reserve the sauce.
Place in the oven and bake for 18-22 minutes or until the dough is golden brown.
Serve with the reserved warmed sauce, for dipping.
