Eg, spaghetti (5)
I believe the answer is:
pasta
'eg spaghetti' is the definition.
(spaghetti is a kind of pasta)
This is the entire clue.
(Other definitions for pasta that I've seen before include "Spaghetti, perhaps" , "Dried flour paste used in cooking Italian dishes" , "Eg, tagliatelle" , "Dish of dough made with durum wheat" , "Macaroni, for example" .)
