Prosciutto, eg (3)
I believe the answer is:
ham
'prosciutto eg' is the definition.
(I know that prosciutto is a type of ham)
This is the entire clue.
(Other definitions for ham that I've seen before include "One of Noah's sons" , "A poor actor - overdoes it" , "Noah's second son - a bad actor?" , "one rescued from flood" , "Overacting pig?" .)
