Mischievous goddess had some food (3)
I believe the answer is:
ate
This clue is a double definition.
'mischievous goddess' is the first definition.
(Greek goddess of mischief)
'had some food' is the second definition.
(to eat is to have food)
(Other definitions for ate that I've seen before include "Tea (anag.)" , "included in one's diet" , "Consumed food" , "upset > Greek goddess" , "Devoured" .)
