Dumping a small pack of roasted, salted peanuts into a bottle of Coke or Dr. Pepper was a favorite oddity that I recall from childhood. Seems like everybody did it. Quite good. You don’t see it anymore because it doesn’t work in anything but the individual size glass bottles, which are not very easily found in most locations.
Sharp cheddar on certain sweets was common in my house, on apple pie, in those cream-filled soft oatmeal cookies, sometimes baked into the crust of fruit dishes, I think baking it in is a throwback to the early German settlers of the area.
Raw celery stalks work nicely with peculiar things, peanut butter, pimento cheese, cream cheese. Great snack on a hot day, very cooling.
Lightly sprinkling sugar and apple cider vinegar over sliced tomatoes can be surprisingly good and is apparently unusual.
French fries with mayo as a dip is good, not uncommon in other countries but odd here.
The new tiny “health conscious” bottles of soda would be amenable to the peanut treatment I suppose.
Celery filled with PB or Cheese Whiz or something similar was a grade school lunch staple. Put raisins on it and you had what the lunch ladies called ants on a log.
I was too squeamish to eat lunch room pizza, though. I begged not to have to waste it, but no choice.
Look for someplace that sells "Mexican" Coca Cola; they come in small glass bottles -- using real sugar instead of whatever Americanese Coke has.
Our local Walmart carries it -- but we've got a ton of Mexicans in the area.
Anything with pimento cheese is good to go.
A little unusual seperately but if you throw them all in a blender I suppose you've basically got ketchup.
