Vegetable from Kenya Biden chewed (6,4)
I believe the answer is:
kidney bean
'vegetable' is the definition.
(kidney bean is a kind of vegetable)
'kenya biden chewed' is the wordplay.
'chewed' indicates anagramming the letters.
'kenya'+'biden'='kenyabiden'
'kenyabiden' with letters rearranged gives 'KIDNEY-BEAN'.
'from' is the link.
(Other definitions for kidney bean that I've seen before include "legume" , "Red pulse" , "Vegetable" , "Pulse (of a renal shape?)" .)
