Step #2 Coat baking sheet with nonstick cooking spray.
Step #3 Place frozen bread dough on greased baking sheet & allow to thaw covered with a cloth for 1 to 2 hrs.
Step #4 In a medium skillet, cook sausage & onion over med-heat/flame until brown & drain fat.
Step #5 Roll thawed bread dough on a lightly floured surface to make a flat rectangular crust 10 inches by 13 inches.
Step #6 Spoon sausage & onion mixture evenly over prepared dough leaving 1/2 inch to 1 inch of room along the outer edges.
Step #7 Scatter pepperoni over the sausage.
Step #8 Sprinkle top all the seasonings over the toppings, along with both kinds of cheese.
Step #9 Wet all of the edges of the dough with water & then starting at one of the short ends, carefully begin rolling the rectangle of dough toward the other end (like a dessert cake roll) pinching the sides to seal.
Step #10 Seal & flatten the ends of the sandwich, folding them under & turning sandwich over so all seams are now on the bottom.
Step #11 Brush the entire sandwich with the beaten egg & bake this at 350ְ for 30 mins.
Step #12 Allow to cool for 10 mins to allow cheese & ingredients to set up before cutting & serving.
