mayo with a little mustard and ketchup. every now and then a bit of dill relish. i don't eat hot dogs very often so i tend to always eat the same thing on them. sometimes if i'm at a restaurant with special toppings i'll add cheese and maybe sauteed shrooms or onions. i want to branch out and try weird things but i'm a pansy when it comes to hot dogs (or burgers)...i like what i like and i tend to stick to that cause i'm always craving it.
i also prefer hebrew national because that way i know it doesn't have pork.
thankfully most vendors and restaurants i've been to nowadays use hebrew national.
