Unload bananas, ripe on one side with lumps (7)
I believe the answer is:
nodular
'with lumps' is the definition.
(I've seen this before)
'unload bananas ripe on one side' is the wordplay.
'bananas' indicates an anagram (bananas can informally mean crazy).
'on one side' indicates taking the first letters (one side of the word).
The initial letter of 'ripe' is 'r'.
'unload' anagrammed gives 'nodula'.
'nodula'+'r'='NODULAR'
(Other definitions for nodular that I've seen before include "Knotted" , "Lumpy" , "Like a small swelling" , "Having tiny knots" , "Like knots" .)
