"Nobody.....I mean NOBODY puts ketchup on a hotdog....Harry Callahan"
Having quoted that, I like them 2 ways---mustard, ketchup, and slaw (the good homemade stuff, not that Ruth's crap)---and--mustard, chili, onions, and slaw. I'll do relish if there's no slaw. Kinda like a Carolina Burger, but its a Carolina Dog
Too much of any ingredient overpowers the dog for me.
Two favorites--Carolina Packers red dogs (ya gotta be raised on it) and Nathans
And always grilled to 1/2 burnt--steamed bun---cold beer
