Mixed greens (5)
I believe the answer is:
salad
'mixed greens' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for salad that I've seen before include "Raw vegetable dish" , "Mainly raw cold dish" , "Counter serving cold vegetable dishes" , "Raw, green, veg" , "Cold vegetable dish" .)
