You have a hot dog and only one condiment; what is it?

Relish...

Can never go wrong with ketchup.

If I can saute some vedallia onion- that's my answer. 

Mustard.

Ketchup, although that's pretty tough. I love a good amount of mustard on there too to balance the flavor out a bit. Don't think I could go pure mustard though, so ketchup it is.

Ketchup? Ketchup! You're all out of your minds. True connoisseurs know mustard goes on a hot dog.

Never put ketchup on a hot dog

I accidentally somehow clicked pickle-relish, but it would be ketchup

Deli mustard. Regular mustard is gross without any other condiment to go with it.
If no deli mustard then just ketchup.

I would say ketchup or mustard.. but sauerkraut has crunch, and can kick the ass out of ketchup and mustard.. so I voted for it.

If I had to pick only one, then it would be raw onions.  I like the added texture and flavor.

Mustard.

Wasabi

Mustard (stadium).

No chili option?

Shit's getting ketchup'd.

Mmmm mustard. Delicious, delicious mustard....

Ketchup.

Lettuce isn't a condiment!

Also, ketchup.

Sauerkraut and pickle relish are amazing but I do love ketchup too.

Ketchup, mustard is not a by itself thing.... for me anyway.

Ketchup all the way.

Moutarde

Mustard always.

Brown Mustard.

Remoulade.

I accidentally voted "tomato" when I really meant "tomato sauce".

I guess the word "ketchup" would be closer to what I was really  looking for.

No Cincinnati style chili?  Blasphemous!!!

Good that ketchup is winning.

mustard. it only makes sense

I like my hot dogs clean.

I picked mustard, but I am kinda wishing I chose onion.

Ketchup FTW! 

I went for mustard, but given the choice, some onions, mustard and ketchup would be pretty sweet. 

Nothing. Just a bare-ass hot dog.

"   Mustard.

Ketchup.

Lack of potato salad makes me sad

Pants and then I burn it.

Hot dogs are sickening.

What, no bostongurka?
" Bostongurka (Swedish meaning "Boston cucumber" or "Boston pickle") is a type of pickled cucumber relish with spices such as paprika and mustard seeds. It is so popular in Sweden that it is considered by some to be a generic term."

Mustard by far. 

Why isn't bacon an option!

Where the heck is Chili? Not Chili peppers. I want Chili.

Ketchup, but I normally put Ketchup and Mustard, and If I'm lucky BBQ Sauce too ...

" Remoulade. "

I would have to choose ketchup.

Onion.  My usual is Ketchup, Mustard, Onion and then either Coleslaw or Relish.... mmmmm!
