Insipid meat recipe (4)
I believe the answer is:
tame
'insipid' is the definition.
(thesaurus)
'meat recipe' is the wordplay.
'recipe' is an anagram indicator.
'meat' anagrammed gives 'TAME'.
(Other definitions for tame that I've seen before include "Broken in" , "Restrained" , "Flat" , "Domesticated kind of meat" , "Submissive -- pedestrian" .)
