Time to tuck into Indonesian island dish (5)
I believe the answer is:
balti
'dish' is the definition.
(I've seen this before)
'time to tuck into indonesian island' is the wordplay.
'time' becomes 't' (abbreviation).
'to tuck into' indicates putting letters inside.
'indonesian island' becomes 'bali' (island of Indonesia).
't' placed inside 'bali' is 'BALTI'.
(Other definitions for balti that I've seen before include "Type of Pakistani cuisine" , "Indian style of cuisine originating in Britain" , "Hot spicy dish" , "Pakistani curry dish, originating perhaps in 1970s' Birmingham" , "Curry dish cooked and served in a flat-bottomed pot" .)
