Italian left party after serving up hot food (5)
I believe the answer is:
balti
'hot food' is the definition.
'italian left party after serving up' is the wordplay.
'italian' becomes 'it'.
'left party' becomes 'lab' (abbreviation for Labour Party**).
'after' is a charade indicator (letters next to each other).
'serving up' is a reversal indicator.
'it'+'lab'='itlab'
'itlab' written backwards gives 'BALTI'.
(Other definitions for balti that I've seen before include "Indian restaurant cooking style" , "Hot spicy dish" , "Indian style of cuisine originating in Britain" , "Curry dish cooked and served in a flat-bottomed pot" , "Style of curry" .)
