Grease a 12-inch skillet. Prepare pizza crust according to package directions. Line bottom and 1/2 inch up the sides of the skillet with dough. Beat eggs, milk, dry mustard, and pepper in medium bowl. Slowly pour egg mixture over crust. Sprinkle bacon and cheeses evenly over the eggs. Cover and cook over medium heat for 15 minutes or until crust is brown on the bottom. Slide out onto cutting board and cut into wedges.
