Satisfy anthropoid full of legumes (7)
I believe the answer is:
appease
'satisfy' is the definition.
(appeasing is a kind of satisfying)
'anthropoid full of legumes' is the wordplay.
'anthropoid' becomes 'ape' (synonyms).
'full of' means one lot of letters goes inside another.
'legumes' becomes 'peas' (I've seen this before).
'ape' placed around 'peas' is 'APPEASE'.
(Other definitions for appease that I've seen before include "be satisfying" , "Make peace with" , "Placate by making concessions" , "Pacify with concessions" , "Mollify, placate" .)
