Heat a large skillet over medium-high heat. Add breakfast sausage and cook, breaking apart with a spatula, until browned and crisp in spots, about 5–7 minutes. Do not drain the fat.
02 -
Stir flour into sausage and rendered fat, cooking for 2–3 minutes to eliminate raw flour taste. Gradually whisk in whole milk. Reduce to medium-low heat and stir continuously until gravy thickens, around 4–5 minutes.
03 -
Remove skillet from heat. Incorporate seasoned salt, black pepper, and if using, rosemary and sage. In a separate skillet, scramble the 5 eggs to your preferred consistency and set aside.
04 -
Preheat oven to 190°C. In a large mixing bowl, blend flour and salt. Using a fork or pastry cutter, work in shortening and cold butter until mixture resembles pea-sized crumbs.
05 -
In another bowl, whisk together 1 egg, white vinegar, and cold water. Add mixture to the dry ingredients and stir until a cohesive dough forms.
06 -
Divide dough in half. On a lightly floured surface, roll out one half to 3 mm thickness. Cut into 7.5 x 10 cm rectangles; repeat with remaining dough. Each pop-tart requires two rectangles.
07 -
Arrange half the rectangles on parchment-lined baking sheets. Brush edges with egg wash. Spoon a portion of scrambled eggs and sausage gravy onto each base. Cover with a second rectangle and seal by crimping the edges with a fork.

Brush tops with egg wash. If desired, top with cheese and sprinkle with seasonings. Bake for 25 minutes, until pastry is golden brown. Cool for 5 minutes before serving.
