Dread changing after church to get something to eat (7)
I believe the answer is:
cheddar
'something to eat' is the definition.
(cheddar is a kind of food)
'dread changing after church' is the wordplay.
'changing' indicates an anagram.
'after' is a charade indicator (letters next to each other).
'church' becomes 'ch' (common abbreviation**).
'dread' anagrammed gives 'eddar'.
'eddar' after 'ch' is 'CHEDDAR'.
'to get' acts as a link.
(Other definitions for cheddar that I've seen before include "Somerset village" , "part of ploughman's lunch" , "Firm cheese originally from Somerset" , "Reddish cheese of English origin" , "Popular cheese originally from Somerset" .)
