I’m currently in the US staying with my girlfriend (we’re in a long-distance relationship) and her family. Been here for a month, have 2 more to go. Where I’m from (Romania) “breakfast foods” are not a thing. Breakfast is a full, proper meal just like lunch and dinner. Since being here, I haven’t been able to get accustomed to the concept of “breakfast foods”. Cereal, pancakes, waffles, bacon, eggs, toast, sandwiches, etc. These are like side dishes or snacks to me. I just don’t feel sated. Gave up on that. Now I’m back to eating what I normally do for breakfast: steak, pasta, rice, soup, stew, chicken, fish/seafood, etc.
I often make things like pancakes, or fried eggs with bacon for supper/dinner. My ex wife would look at me like I was crazy.
But I just asked her, what makes a breakfast food a “breakfast” food other than social convention? Eat whatever you want whenever you want. It’s quite literally in the who cares category of let people live their lives.
