Why are pork and fish in various forms normal for breakfast when chicken or lamb would be viewed as odd by most people (in the UK I mean)?
Also why are things like leftover curry/pizza/Chinese so good for breakfast? I also happen to think chocolate tastes its best if it’s the first thing you’ve eaten that day.
But please don’t get me started on ‘breakfast biscuits’ 
What’s your favourite breakfast? Is it something unacceptable?
