In a large mixing bowl, whisk together the all-purpose flour, salt, granulated sugar, and baking powder. Using a pastry cutter or fork, blend in the cold cubed butter until the mixture has a coarse, crumbly texture. In a separate bowl, combine the whole milk and 1 large egg, then add to the dry ingredients. Mix until a soft dough forms.

Transfer the dough onto a lightly floured work surface. Knead gently, then roll out to approximately 1/4-inch thickness. Cut the dough into 6 to 8 equally sized rectangles.

In a medium bowl, combine the crumbled cooked sausage, shredded cheese, scrambled eggs, and Dijon mustard if desired.

Spoon a portion of filling onto one half of each dough rectangle, leaving a margin along the edges. Fold the dough over the filling and press the edges firmly with a fork to seal.

Arrange the filled pastries on a parchment-lined baking sheet. Brush the surface of each with the beaten egg to promote a glossy, golden finish.
