In center of parchment paper, place 1/4 of the pasta with 1/4 of the meatballs on top. Dust with parmesan cheese and julienne basil. Fold over parchment paper, one corner to opposite corner (resembling a triangle). Start from one side, folding over in small increments, encapsulating the pasta and meatballs inside. Keep folding and creasing until complete, and the triangle now looks like a half dome.
