Bit of food delivered to church (5)
I believe the answer is:
piece
'bit of' is the definition.
(I've seen this before)
'food delivered to church' is the wordplay.
'food' becomes 'pie' (pie is a kind of food).
'delivered to' means one lot of letters go next to another.
'church' becomes 'ce' (abbreviation for Church of England).
'pie'+'ce'='PIECE'
(Other definitions for piece that I've seen before include "Component; portion" , "one of eight once ready for the Spanish?" , "Segment" , "Scrap - musical work" , "Section; firearm" .)
