Turn on the oven to 375°F Grease a pizza pan with shortening.
Put thawed bread dough on the pizza pan. Fatten the dough slightly. Use your hands to press the dough into the pizza pan, covering the pan completely. (Sprinkle flour over your hands if dough is sticky.) With your fingers press edges up into a rim. Prick dough generously with the fork. Put pizza pan in oven. Bake for 15 to 20 minutes or until pizza crust is light brown. Use hot pads to remove pizza pan from oven. Place on a cooling rack.
Use scissors to cut bacon into bite-size pieces. Put bacon pieces, frozen potato mixture, and black pepper in a medium skillet. Put skillet on a burner. Turn burner to medium-high heat. Cook and stir with a wooden spoon about 5 minutes or until bacon pieces are crisp and potatoes are tender. Turn off burner. Remove skillet from burner. Place a colander over a bowl. Spoon potatoes and bacon into the colander and let the fat drain into the bowl. Save potatoes and bacon until Step 8. Put fat in a container to throw away.
Crack eggs in a medium bowl. Add the milk. Use a whisk to beat the eggs and milk together.
Put butter in a large skillet. Put skillet on burner. Turn burner to medium heat. Melt the butter. When butter is melted, pour the egg mixture into the skillet. Cook, without stirring, until egg mixture begins to et on the bottom and around the edges.
Use a pancake turner to lift and fold partially cooked eggs so that the uncooked portion flows underneath. Continue cooking over medium heat for 2 to 3 minutes or until the egg mixture is cooked through but still glossy and moist. Turn off the burner. Remove skillet from burner.
Sprinkle half of the shredded cheese over the bake pizza crust. Top with scrambled eggs, cooked bacon and potato mixture, and the rest of the shredded cheese. Using hot pads, put pizza pan in oven. Bake pizza for 5 to 8 minutes or until cheese is melted and bubbly. Turn off oven. Use hot pads to remove pizza pan from oven. Let stand on the cooling rack for 2 minutes before serving.
