Crossword Genius

Celebration justifies tasty sandwiches (6)

Ross

I believe the answer is:

fiesta

'celebration' is the definition.
(fiesta is a kind of celebration)

'justifies tasty sandwiches' is the wordplay.
'sandwiches' indicates a hidden word (the answer is sandwiched in by the clue).
'FIESTA' is hidden within 'justifies tasty'.

(Other definitions for fiesta that I've seen before include "celebration abroad" , "(Spanish) religious festival" , "Public celebration in Spain" , "Spanish holiday" , "Elaborate public party, in Spain perhaps" .)

I've seen this clue in The Times.
