Light lunches (6)
I believe the answer is:
salads
'light lunches' is the definition.
(I've seen this in another clue)
This is the entire clue.
(Other definitions for salads that I've seen before include "Cold dishes with lettuce etc" , "Food mixtures of lettuce etc." , "Cold dishes of vegetables or fruits" , "Dishes of letuce etc." , "Food mixtures including greens" .)
