Unexciting meat recipe (4)
I believe the answer is:
tame
'unexciting' is the definition.
(similar in meaning)
'meat recipe' is the wordplay.
'recipe' indicates anagramming the letters.
'meat' is an anagram of 'TAME'.
(Other definitions for tame that I've seen before include "Broken in" , "Not exciting; domesticate" , "Not exciting; cooperative" , "Not wild, unexciting" , "Restrained" .)
