Hiking interminably, brought up so-called breakfast option (6,5)

'breakfast option' is the definition.
The answer and definition can be both things that one consumes for nourishment as well as being singular nouns.
Perhaps they are linked in a way I don't understand?

'hiking interminably brought up so-called' is the wordplay.
'hiking interminably' becomes 'raisin' (I can't justify this - if you can you should believe this answer much more).
'brought up' becomes 'bred' (to breed is to bring up or raise).
'so-called' indicates a 'sounds like' (homophone) clue.
'bred' is a homophone of 'bread'.
'raisin'+'bread'='RAISIN BREAD'
