1Heat oven to 400°F. Spray large cookie sheet with cooking spray.
2In medium bowl, beat eggs, milk and pepper with whisk or fork until well blended. In 10-inch nonstick skillet, melt butter over medium heat. Add egg mixture; cook 3 to 5 minutes, stirring occasionally, until eggs are set but moist.
3Unroll dough on large cutting board; pat into 14x10-inch rectangle. Cut dough into 4 (7x5-inch) rectangles. Sprinkle 2 tablespoons mozzarella cheese on half of each rectangle to within 1/2 inch of edges. Top evenly with pepperoni, Parmesan cheese and eggs. Fold plain half of dough over filling; press edges firmly with fork to seal. Place on cookie sheet.
4Bake 11 to 13 minutes or until golden brown.
