Orzo or ziti (5)
I believe the answer is:
pasta
'orzo or ziti' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for pasta that I've seen before include "Staple food of Italy" , "Macaroni, for example" , "Dish of dough made with durum wheat" , "Fare from Italy" , "Basis for serving" .)
