Greek salad topper
I believe the answer is:
feta
'greek salad topper' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for feta that I've seen before include "10 down cheese" , "Salty Greek cheese" , "Greek cheese from goat or sheep milk" , "White and salty goat or sheep cheese" , "Greek 8 across" .)
