A bite to eat (6)
I believe the answer is:
canape
'a bite to eat' is the definition.
(a canape is a type of snack)
This is all the clue.
(Other definitions for canape that I've seen before include "Finger food for parties" , "Savoury party fare" , "Savoury nibble offered at posh parties" , "Hors d'oeuvre" , "Savoury mouthful" .)
