Spicy samosa is too much for him (4)
I believe the answer is:
amos
'him' is the definition.
'spicy samosa is too much' is the wordplay.
'is too much' indicates a hidden word (the clue hides the answer plus unneeded letters).
'AMOS' is hidden in the letters of 'spicy samosa'.
'for' is the link.
(Other definitions for amos that I've seen before include "Old Testament prophet" , "30th OT book" , "Part of bible" , "Hebrew prophet" , "Biblical character" .)
