Ziti shapes are a type of pasta that are tubular in shape. They are often used in Italian dishes such as baked ZITI and can be found in many grocery stores. ZITI shapes are also known as penne, which is the Italian word for 'PEN'. The term 'ZITI' comes from the Italian word for 'BUNDLE' and refers to the way the pasta is bundled together. ZITI shapes are usually made from durum wheat semolina and are cut diagonally at both ends.
