Crush food prepared and consumed with right filling (10)
I believe the answer is:
dishearten
'crush' is the definition.
'food prepared and consumed with right filling' is the wordplay.
I cannot really see how this works, but
'food' could be 'heart' (heart is a kind of food) and 'heart' is found within the answer.
'and' could be 'n' (common abbreviation for 'and') and 'n' is found within the answer.
This may be the basis of the clue (or it may be nonsense).
Can you help me to learn more?
(Other definitions for dishearten that I've seen before include "Put a damper on" , "cast down" , "Bring down" , "dismay?" , "Take hope from" .)
