Farfalle for one (5)
I believe the answer is:
pasta
'farfalle for one' 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 "E.g. fusilli" , "Spaghetti, orzo etc" , "Dried flour paste, staple in Italian food" , "Linguine, e.g." , "Staple food of Italy" .)
