Teresa distributed, for example, good seasonal gift (6,3)
I believe the answer is:
easter egg
'seasonal gift' is the definition.
(I've seen this before)
'teresa distributed for example good' is the wordplay.
'distributed' is an anagram indicator.
'for example' becomes 'eg' ('e.g.' can be a synonym of 'for example').
'good' becomes 'g' (abbreviation).
'teresa' with letters rearranged gives 'easter'.
'easter'+'eg'+'g'='EASTER EGG'
(Other definitions for easter egg that I've seen before include "Seasonal fare" , "Seasonal gift" , "Seasonal present" , "festive gift" , "seasonal treat" .)
