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.
Funny, I’m the opposite - I get stuffed from a breakfast of bacon, eggs, and toast/biscuit/hashbrowns, whereas I don’t tend to eat nearly as much at other meals.
I also love breakfast foods. Eggs are life.
I travel a bunch and have lived abroad and I always consistently only ever miss breakfast restaurants/diners and breakfast foods.
