Preheat your oven to 425°F (220°C) and line a baking sheet with parchment paper.

Roll out the pizza dough to a rectangle about ¼-inch thick and slice into 15 equal strips.

Wrap each sausage frank tightly with a strip of dough, pinching ends to seal.

In a large saucepan, bring 10 cups of water to a boil and stir in ¾ cup of baking soda. Boil the wrapped sausages in batches for 20-30 seconds.

Transfer boiled Pretzel Dogs onto the prepared baking sheet, brush with beaten egg, and sprinkle with kosher salt.

Bake for 20-21 minutes or until deep golden brown.

Allow to cool slightly before serving warm with mustard or cheese sauce.
