Breakfast time? (8)
I believe the answer is:
porridge
I believe this is a double definition.
'breakfast' is the first definition.
(porridge might be eaten for breakfast)
'time?' is the second definition.
(I've seen this before)
(Other definitions for porridge that I've seen before include "that's served at Her Majesty's pleasure?" , "Hot breakfast food" , "Eat for breakfast in prison" , "Breakfast food - prison term" , "Breakfast food - time inside" .)
