The usual sandwiches put out with a spicy snack (6)
I believe the answer is:
pakora
'spicy snack' is the definition.
(battered Indian snack)
'the usual sandwiches put out with a' is the wordplay.
'the usual' becomes 'par' (par for the course).
'sandwiches' indicates putting letters inside (goes on either side like a sandwich).
'put out' becomes 'ko' (abbreviation for knock out).
'with' means one lot of letters go next to another.
'par' going around 'ko' is 'pakor'.
'pakor'+'a'='PAKORA'
(Other definitions for pakora that I've seen before include "Indian food" , "Indian dish of vegetables or meat deep-fried in spiced batter" .)
