Extra violinists provide pasta dish (7)
I believe the answer is:
ravioli
'pasta dish' is the definition.
(I've seen this in another clue)
'extra violinists provide' is the wordplay.
'provide' indicates a hidden word.
'RAVIOLI' is hidden in the letters of 'extra violinists'.
(Other definitions for ravioli that I've seen before include "Filled pasta dish" , "Filled pasta envelopes" , "Filled pasta squares" , "Filled type of pasta" , "which Verdi may have put away" .)
