2Beat the egg and water in a small bowl with a fork. Set aside.
3Sprinkle the work surface with the flour. Unfold 1 pastry sheet on the floured surface. Roll the pastry sheet into a 9x12-inch rectangle. Cut the rectangle into 12 (3-inch) squares. Repeat with the remaining pastry sheet, making 24 squares in all.
4Stir the cream cheese, shredded sheese, garlic and bacon in a medium bowl.
5Spoon about 2 teaspoons cheese mixture into each pepper half.
6Place 1 filled pepper half diagonally, cheese-side down onto each pastry square. Fold the pastry up over the peper and press firmly to seal.
7Brush the filled pastries with the egg mixture.
Sprinkle with additional shredded cheese, if desired.
8Place the pastries onto 2 baking sheets.
9Bake for 20 minutes or until the pastries are golden brown. Let the pastries cool on the baking sheets on wire racks for 10 minutes.
