Indian food served in second half (4)
I believe the answer is:
dhal
'indian food' is the definition.
'in second half' is the wordplay.
'in' indicates a hidden word.
'DHAL' can be found hidden inside 'second half'.
'served' is the link.
(Other definitions for dhal that I've seen before include "Indian dish of dried seeds" , "Pigeon-pea" , "Indian dish of dried pulses" , "Split pulses (in Indian cookery)" , "pulse" .)
