What's the worst sandwich you've ever had?

Moldy pre made turkey club from a grocer = food poisoned
That knuckle sandwich back in ‘95 from my older brother is still the worst sandwich to date
The one Bekka made for me.
Anything with rye bread.
Egg salad. Greatly dislike eggs. 🤮
2 piece bread with your imagination in the middle. Hard times 😂
The one I had today. Routine: make ham sandwiches for work, put them in an old bread bag, eat for lunch. Except today, I brought the wrong half of the loaf.. Bread, no ham, no butter.. 🙁
