In short, hurry up to get the fellow something to eat (6)
I believe the answer is:
quiche
'something to eat' is the definition.
(quiche is a kind of food)
'in short hurry up to get the fellow' is the wordplay.
'in short' means to remove the last letter.
'hurry up' becomes 'quick'.
'to get' is a charade indicator (letters next to each other).
'the fellow' becomes 'he' (he refers to a man).
'quick' with its last letter taken off is 'quic'.
'quic'+'he'='QUICHE'
(Other definitions for quiche that I've seen before include "Tart filled with savoury ingredients" , "Egg dish" , "food" , "Cheese and bacon pastry dish" , "Open tart with egg filling" .)
