Making your homemade savory breakfast pop tarts with bacon & egg is a straightforward process if you follow these steps:

1. Prepare the Dough: In a large bowl, combine the flour, salt, and sugar. Add the chilled butter and mix with a pastry cutter until the mixture resembles coarse crumbs.
2. Add Water: Gradually add cold water, a tablespoon at a time, mixing until the dough comes together. You want it to be moist but not sticky.
3. Chill the Dough: Form the dough into a ball, wrap it in plastic wrap, and refrigerate for at least 30 minutes.
4. Preheat Oven: Preheat the oven to 400°F (200°C) while the dough chills.
5. Prepare Filling: In a bowl, mix together the crumbled bacon, beaten eggs, shredded cheese, and chives. Season with black pepper to taste.
6. Roll Out Dough: On a floured surface, roll out the chilled dough to about ¼ inch thick. Cut into rectangles measuring approximately 4×6 inches.
7. Assemble Pop Tarts: Place a tablespoon of the filling in the center of half the dough rectangles. Leave a border around the edges.
8. Seal the Edges: Place another rectangle on top of each filled rectangle. Press the edges with a fork to seal.
9. Create Vent Holes: Use a sharp knife to cut a few small slits in the top of each pop tart for steam to escape during baking.
10. Bake: Arrange the pop tarts on a baking sheet lined with parchment paper. Bake for 25-30 minutes or until golden brown.
11. Cool and Serve: Remove from the oven and allow to cool slightly before serving.

Each step will guide you in creating these satisfying pop tarts that are sure to impress!
