I’m not that old, but it’s going on for 5 years or so now. We call it a “monte cristo,” but really it’s a ham and cheese fried in egg batter w/ jam and mayo inside. I do switch it up sometimes, but not by request, only because I feel bad, and if I’m making something else for my other kids, I’ll just send the same thing with all of them. I ask what they want on weekends when I have more time to make lunch, and it’s usually the same thing (or leftover pizza or mac 'n cheese if that’s an option).

My brother did closer to that. He had chicken patty sandwiches all through high school, a lot of middle school, and probably college. He’d throw a patty into the microwave for 1-2 min, put it on bread, then go to school. I think it was PB&J most of the time before that. When he was single, he would get double stacks from Burger King instead almost every day for lunch because they cost like $1 each and there was one near work.

Some people really value simplicity and routine. I’m kind of like that, but instead of making the same thing every time, I grab whatever is easiest. That means a lot of PB (no J) sandwiches and lots of leftovers.
