I'll never understand how can people eat sandwiches every day, especially those with some kind of meat in them. I'm not vegetarian but eating sandwiches for more than two days in a row make me want to puke.
I am one and it’s peanut butter every day. For 3 years basically every working day has had a peanut butter sandwich. And that’s how the next 30 some years are looking too. It’s fine. I can live that way.
I eat sandwiches every day, and the same thing or small variety. I'm not eating for the experience, I'm eating to not be hungry. I can make and eat a sandwich is less than a minute, so I can get back to doing what I want to be doing.
If I really don't feel like a sandwich, there's always toast.
Genuinely, why? Personally, I'm happy to eat basically same meals for a few days before they get boring, and you can vary your sandwiches a lot of you so desire.
Peanut butter? Upgrading to natural peanut butter made all the difference for me, so it’s no longer just for kids.
I even get decent marmalade, which definitely doesn’t work for kids, or a dark amber maple syrup. I currently have apple butter, which goes nicely on a peanut butter sandwich, or with a scoop of cottage cheese on the side
I also eat pretty much the same breakfast every day. For lunch I can vary what's on the bread and the type of bread. That's just how things are here. It's not the nicest, but it saves a lot of time and money and can also be quite nice
