What vegans avoid (4)
I believe the answer is:
meat
'what vegans avoid' is the definition.
(I've seen this in another clue)
This is all the clue.
(Other definitions for meat that I've seen before include "Chops, steaks etc" , "Edible flesh" , "Spam, ham, lamb etc" , "Flesh for eating" , "Animal flesh as food" .)
