Feat, organising Greek export (4)
I believe the answer is:
feta
'greek export' is the definition.
'feat organising' is the wordplay.
'organising' indicates anagramming the letters.
'feat' with letters rearranged gives 'FETA'.
(Other definitions for feta that I've seen before include "Greek dairy product" , "food there" , "Type of cheese" , "Soft Greek cheese" , "Greek cheese from goat or sheep milk" .)
