For some reason, I was thinking about this during my commute to work today. Maybe because I didn't have breakfast. Anyway, what exactly is the definition of breakfast food? Clearly it's anything that you eat for breakfast, but are there some foods that are only breakfast items? Are there other items that cannot be considered breakfast foods? Most would say that steak and potatoes should be served for dinner, but one of the best breakfasts I've ever had was in Western Colorado when we had ribeye steaks and roasted potatoes. So I'm curious what other people think is the definition of breakfast food.
