Food seen on boxer's ear (11)
I believe the answer is:
cauliflower
'food' is the definition.
(cauliflower is a kind of food)
I can't explain the remainder of the clue.
Can you help me to learn more?
(Other definitions for cauliflower that I've seen before include "Auricular deformation seen in boxers and rugby forwards?" , "Battle-scarred lug" , "Variety of cabbage" , "something to eat" , "Large vegetable of cabbage family" .)
