Cut the dough rolls in half and roll each into an oblong shape. Place them in a greased 13x9” pan. Sprinkle on the poppy seeds. Cover and let rise in a warm place until doubled, about 30 minutes.
Place the sausage into a baking dish. When the dough has risen, place both the rolls and the sausages in the oven at 350°F(175°C) for 15 minutes. Remove to a wire rack to cool.
Slice the buns down the middle. Place a sausage in each bun. Top with mustard, relish, onion, tomato, pickle, pepperoncini, and a sprinkle of celery salt.

Notes
For an authentic Chicago dog experience, make sure to include all the classic toppings and apply them in the proper order. Ketchup is a no-go for purist.
There isn't much room on these cute little sliders so make sure to chop the toppings small so that they all fit.
Chop and prepare all your toppings in advance to make assembly quick and stress-free, especially when serving a crowd.
