Over a bowl of cereal breakfast this morning this morning I got to thinking. Yes, dangerous, I know. But I've cereal is sometimes referred to as "Breakfast Food." Then I got to wondering how and why cereal became "breakfast food." Why couldn't I eat it for dinner? And why not eat lunch for breakfast? I've had cold pizza for breakfast. It didn't kill me. Why not have roast turkey, green beans and mashed potatoes for breakfast? Or a bowl of oatmeal for dinner? Would it hurt to have a breakfast burrito for lunch like I did yesterday? Now I can understand that people sometimes take a long time to prepare dinner. Like the roast turkey dinner I mentioned. You don't want to get up at 5:00 AM to make breakfast that won't be ready until 9:00 AM. Especially if you have to be at work at 8:00 AM. But other then habit or cultural reasons, why do we eat what we eat when we eat it?
