Nosh very good that feeds the writer: pasty possibly (4,3)
I believe the answer is:
meat pie
'pasty possibly' is the definition.
(pasty is a kind of meat pie)
'nosh very good that feeds the writer' is the wordplay.
'nosh' becomes 'eat' (I've seen this in another clue).
'very good' becomes 'pi' (pi can mean pious).
'that feeds' is an insertion indicator (one word is fed by another set of letters).
'the writer' becomes 'me' (the person who wrote the clues).
'eat'+'pi'='eatpi'
'eatpi' inserted inside 'me' is 'MEAT-PIE'.
(Other definitions for meat pie that I've seen before include "Ape time (anag.)" , "fare" , "Snack" , "Pastry covered dish containing pork, beef etc" .)
