In a large pan on medium-high heat. Brown the sausage until no pink remains. Set it aside and let the sausage cool slightly.
Preheat oven to 375℉. Roll out your pizza dough on a heavily floured surface until it is about ¼ inch thick in the shape of a pizza. Layer your slices of cheese across the pizza so that they cover as much of the dough as possible. Then sprinkle the parmesan across the dough. Add your cooled crumbled sausage across the dough.
Pull the edges of the dough so there is some space between the cheese/meat and the edge of the dough. Roll the dough into a log or loaf of bread with the seam placed at the bottom so it doesn't unroll. Brush the bread with the egg. Season the top of the bread and place on an oiled baking pan.
Bake in the oven for 30 minutes or until the bread is golden brown. Slice and serve!
Notes
When rolling the dough out, avoid letting it become too thin. The thinner the dough is, the more likely it is to fall apart and break during the cooking process while the bread is expanding.
When transferring the bread from one surface to another, make sure you hold underneath the bread so that it doesn't crack open under the weight of the sausage.
