Opposed to taking the twit back to have food (9)
I believe the answer is:
antipasto
'food' is the definition.
(antipasto is a kind of food)
'opposed to taking the twit back to' is the wordplay.
'opposed to' becomes 'anti' (anti means opposing something).
'taking' is a charade indicator (letters next to each other).
'the twit' becomes 'sap'.
'back' says the letters should be written in reverse.
'sap' backwards is 'pas'.
'anti'+'pas'+'to'='ANTIPASTO'
'have' acts as a link.
(Other definitions for antipasto that I've seen before include "course of hors d'oeuvres" , "Italian dish" , "hors-d'oeuvre" , "Italian appetisers" , "Italian food" .)
