I say, if you want to have dinner food for breakfast, have at it. Research shows that it makes no difference when you eat certain foods of the day. After all, in ancient Roman times, while some of those who where a little more well off would have eaten slightly more prepared meals at night, many had the same cuisine throughout the day, and there was no distinction between Breakfast, Lunch, and dinner.
Besides. When isn't it time for nice, cool one? Sometimes I'll even meet my buddy Normy for a beer during a morning break from delivering the mail.
