Meat displaying no veins (7)
I believe the answer is:
venison
'meat' is the definition.
(I know that venison is a game meat)
'displaying no veins' is the wordplay.
'displaying' indicates anagramming the letters (the anagrammed letters display the answer).
'no'+'veins'='noveins'
'noveins' is an anagram of 'VENISON'.
(Other definitions for venison that I've seen before include "Game" , "Deer (as food)" , "Meat - in ovens (anag)" , "Type of meat" , "Flesh of deer" .)
