It is a regular thing to eat breakfast items for lunch and dinner.
There is no rule stating that if you eat eggs, bacon, or even pancakes, it has to be at breakfast time. Many dishes that my mother makes for us, for example the most recent being the Easter Feast, would sometimes end up looking like a meal that would be eaten at breakfast. Pancakes (flat ones, the Hungarian kinds) would be eaten as dessert for lunch, and sometimes it would be eaten for dinner if there is any left over. For me, coming from a different country, food doesn't vary that much throughout a day. It might be just my family, or me, but I just eat whatever I can fix up.
If I would have to eat something for every single meal for a week, it would be cereal. Like many kids, I love cereal. It is sweet, comes in a variety of different flavors and combinations, and is easy to prepare. I can remember many times when I ate cereal for dinner, or even at lunch one time.
In my opinion, it really doesn't matter what you eat at all. As long as it is healthy and good for you, or your meals are somewhat different throughout the day, you can probably make your hunger go away and provide the energy you need.
