Preheat oven to 375 degrees Fahrenheit.
Unroll dough, and separate into triangles. Press triangles together to form a single 10-inch round crust on a 12-inch pizza pan coated with cooking spray. Crimp edges of dough with fingers to form a rim.
Top prepared dough with potatoes, bacon, and cheddar cheese. Carefully pour egg whites over cheese; sprinkle with salt, pepper, and Parmesan cheese.
Bake at 375 degrees Fahrenheit for 23 minutes or until crust is browned. Cut into wedges.
*Young chefs can unroll the dough and help top it with toppings.
