Unexciting meat dish (4)
I believe the answer is:
tame
'unexciting' is the definition.
(similar in meaning)
'meat dish' is the wordplay.
'dish' indicates anagramming the letters (dish can informally mean to destroy).
'meat' with letters rearranged gives 'TAME'.
(Other definitions for tame that I've seen before include "Domesticated kind of meat" , "Not wild, unexciting" , "quiet" , "Domisticated with meat" , "Domesticated - dull" .)
