Free ticket - Italian dishes? No thanks (4)
I believe the answer is:
pass
'free ticket' is the definition.
(I've seen this in another clue)
'italian dishes? no thanks' is the wordplay.
'italian dishes?' becomes 'pastas' (I've seen this in another clue).
'no' is a deletion indicator.
'thanks' becomes 'ta' (UK informal version of 'thank you').
'pastas' with 'ta' taken away is 'PASS'.
(Other definitions for pass that I've seen before include "Pronounce (judgement)" , "Search me" , "Get beyond" , "Cross-mountain route; permit" , "sticky situation if one is pretty" .)
