Italian staple (5)
I believe the answer is:
pasta
'italian staple' is the definition.
(I've seen this before)
This is the entire clue.
(Other definitions for pasta that I've seen before include "dish from Italy" , "tagliatelle perhaps" , "Dried flour paste, staple in Italian food" , "Dish of dough made with durum wheat" , "E.g. fusilli" .)
