This version of spaghetti and meatballs comes from Abbruzzo but it is eaten all over Italy. Spaghetti alla Chitarra (say key-TAH-rra) is a long pasta that is traditionally made fresh, then rolled into sheets as thick as uncooked spaghetti and pressed onto a chitarra, a frame with many long closely-spaced parallel wires. The resulting spaghetti is square in cross section. The square chitarra pasta has more surface area than round spaghetti so it holds more sauce.
Spaghetti alla chitarra is served many ways, but one of the most traditional ways is with a simple tomato sauce and tiny meatballs called pallottine.
