In a skillet over medium-high heat, cook and crumble the breakfast sausage until browned, about 5 to 7 minutes. Do not drain rendered fat.

Sprinkle all-purpose flour over the cooked sausage and stir to absorb the fat, cooking for an additional 2 to 3 minutes. Gradually whisk in the whole milk and cook over medium-low heat, stirring frequently, until the mixture thickens, 4 to 5 minutes.

Remove skillet from heat and stir in seasoned salt, black pepper, and, if using, the fresh rosemary and dried sage. Set aside to cool slightly.

In a separate pan, scramble the eggs over medium heat to desired doneness. Remove from heat and set aside.

Preheat the oven to 375 degrees Fahrenheit (190 degrees Celsius). In a large bowl, combine all-purpose flour and salt. Cut in the vegetable shortening and cold butter until the mixture resembles coarse crumbs.

Arrange half of the dough rectangles on a lined baking sheet. Brush edges with egg wash. Place a spoonful of scrambled eggs and sausage gravy in the center of each rectangle. Top with a second dough rectangle and seal the edges with a fork.
