Vegetable mix (5)
I believe the answer is:
salad
'vegetable mix' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for salad that I've seen before include "Mainly raw cold dish" , "Lettuce, cucumber etc" , "A cold meal with lots of lettuce" , "Cold vegetable dish" , "Curve" .)
