Preheat oven to 425°F* and line a large baking sheet with parchment paper. Spray with nonstick cooking spray.
Sprinkle flour onto a cutting board. Remove the pizza dough from the package and place it onto the board. Using a rolling pin, roll the dough out into a 20x14-inch rectangle. Using a pizza cutter, cut the rolled-out dough into 4, 5-inch wide strips.
On each strip of dough, add ½ cup of scrambled eggs, ½ cup of cheese, and 2 tablespoons of crumbled bacon. Tightly roll the filling in the dough until it is completely wrapped, pinching the ends together to seal.
To a medium saucepan over medium heat, add water. Bring the water to a light boil. Add the baking soda and stir until dissolved.
Working one at a time, add a pretzel roll to the boiling water and boil for 20 seconds. Using a slotted spoon, remove the pretzel roll and place it on the parchment-lined baking sheet. Repeat with the remaining pretzel rolls.
Use a pastry brush to brush the outside of each with the beaten egg. Sprinkle each evenly with salt.
Using a sharp knife, cut three diagonal slits on the top of each roll.
Bake for 15-17 minutes, or until the dough is golden brown.
In the final minutes of baking the pretzel rolls, combine the melted butter with salt.
Brush the baked pretzel rolls with the butter mixture and serve garnished with parsley. (optional)
