Healthy — well done! (4,3,3)
I believe the answer is:
good for you
I believe this is a double definition.
'healthy' is the first definition.
(synonyms)
'well done' is the second definition.
(I've seen this before)
(Other definitions for good for you that I've seen before include "congratulations" , "wholesome" , "Very fatty steak may not be" , "like a healthy steak?" , "Generally, fruit and veg is" .)
