Preheat oven to 400 degrees F. Line a baking sheet with foil, grease, and set aside. Unroll thawed pizza dough onto a lightly floured surface. Roll dough into a 12-inch square. Spread orange marmalade evenly over dough. Cut dough into nine 4-inch squares.
For filling: in a medium bowl, stir together the bacon, cheese, and green onions. Place 3 tablespoons filling on each dough square. Sprinkle each lightly with pepper. Fold one corner of each dough square over filling to opposite corner. Use the tines of a fork to press edges to seal. Prick tops of turnovers with the fork.
Place turnovers on prepared baking sheet. Brush with milk and sprinkle with poppy seeds and/or sesame seeds. Bake in a 400 degrees F oven for 12 to 15 minutes or until golden (filling may leak out slightly).
