Consume tons in peeled bananas (7)
I believe the answer is:
deplete
'consume' is the definition.
('deplete' can be a synonym of 'consume')
'tons in peeled bananas' is the wordplay.
'tons' becomes 't'.
'in' is an insertion indicator.
'bananas' indicates anagramming the letters (informal term for mad).
'peeled' is an anagram of 'deplee'.
't' put inside 'deplee' is 'DEPLETE'.
(Other definitions for deplete that I've seen before include "Use up, reduce in quantity" , "Reduce the number of" , "Reduce the quantity of (resources)" , "Drain" , "Use up quantities of, reduce store" .)
