The man gets sesame seed (6)
I believe the answer is:
lentil
'seed' is the definition.
(I've seen this before)
'the man gets sesame' is the wordplay.
'the man' becomes 'len' (I've seen this in other clues).
'gets' is a charade indicator (letters next to each other).
'sesame' becomes 'til' (I've seen this in another clue).
'len'+'til'='LENTIL'
(Other definitions for lentil that I've seen before include "A legume, its seed" , "Type of soup" , "Pulse used in cooking" , "'Seed, pulse (6)'" , "Pulse for soup etc" .)
