Spaghetti, e.g. (5)
I believe the answer is:
pasta
'spaghetti eg' is the definition.
(spaghetti is a kind of pasta)
This is the entire clue.
(Other definitions for pasta that I've seen before include "dish from Italy" , "Plain food" , "Course of Italian" , "eg Tortellini" , "dish that's Italian" .)
