How steak may be good for you
I believe the answer is:
well-done
'how steak may' is the definition.
I can't judge whether this defines the answer.
'good for you' is the wordplay.
'good' becomes 'well' ('well' can be a synonym of 'good').
'for you' becomes 'done' (I am not sure about this - if you are sure you should give a lot more credence to this answer).
'well'+'done'='WELL-DONE'
'be' is the link.
Can you help me to learn more?
(Other definitions for well-done that I've seen before include "Bravo" , "Commendation for achievement" , "Thoroughly cooked or meritoriously accomplished" , "Congratulations - certainly not rare!" , "Congratulations - cooked right through" .)
