Step 1

Preheat the oven to 350 degrees F. Line a baking sheet with parchment paper. Place the hot dog buns side by side on the baking sheet. In a small bowl, beat together the 1 egg. Brush the top sides of the buns with the egg wash and sprinkle on the poppy seeds. Transfer to the oven to bake for 5 minutes. Remove and set aside.

Step 2

Bring a medium pot filled with water to a boil. Drop the hot dogs into the water and then immediately cover, turn off the heat and allow to stand for 5 minutes. Place the hot dogs inside each of the hot dog buns. Top each hot dog with a squiggle of yellow mustard. Then, add a handful of diced onion, a teaspoon of sweet relish, a few pepperoncini, tomatoes and a dill pickle. Add a pinch of celery salt to each hot dog. Eat and serve immediately.
