I’m always in the mood for a great hot dog. They make for a great quick lunch. And even though I do occasionally make my dogs ‘traditional’, with just mustard, I really like to jazz them up a bit. Like these still-easy-to-make but fantastic blackjack hot dogs. First, you can’t go wrong with sauteed onion on a dog. It’s the perfect pairing. To offset a bit of that onion sweetness throw in some pepperjack cheese and the crunch of fresh tomato. Finally, top it all off with a kicked up mustard.

Grab Some Spicy Mustard
I used my favorite mustard, Zatarain’s Creole mustard, which has tremendous flavor. It is a little spicy, but not overwhelmingly so. I keep several squeeze bottles on hand at all times (it lasts darned near forever in the pantry) for my Blackjack Hot Dogs and a whole bunch of other things!
