A vegan wouldn’t take it away for a bit of a meal (5)
I believe the answer is:
offal
'a vegan wouldn't take it' is the definition.
I can't judge whether this defines the answer.
'away for a bit of a meal' is the wordplay.
'away' becomes 'off' ('off' can be a synonym of 'away').
'for' says to put letters next to each other.
'a bit of a meal' becomes 'al' (I can't justify this - if you can you should give a lot more credence to this answer).
'off'+'al'='OFFAL'
Can you help me to learn more?
(Other definitions for offal that I've seen before include "Entrails used as food" , "Liver, lights, etc" , "Edible innards" , "Edible insides" , "Edible internal parts" .)
