Healthy meal (5)
I believe the answer is:
salad
'healthy meal' 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 "Green, potato, Russian or Waldorf?" , "Food dish" , "rabbit food" , "See 1 ac" , "A cold meal with lots of lettuce" .)
