Preheat oven to 425˚F
Combine filling ingredients in a large mixing bowl and completely mix together. Set aside.
To assemble: Roll 1 chilled dough out onto a lightly floured surface into a 13” x 9” rectangle and brush surface with egg wash.
Scoop filling into a piping bag or resealable plastic bag and cut a ½ inch opening at the tip.
Leaving a ½ inch border around the edge and beginning on the left (13 inch) edge, pipe 8 lines of filling, 2 inches apart.
Roll other disc of dough to a 13”x 9” rectangle. Sprinkle sesame seeds over dough and using a rolling pin, gently embed sesame seeds into dough.
Carefully lift and place sesame studded dough over filling topped dough and gently press down between filling and edge to seal.
Slice to separate each hand pie stick and using the back of a fork, crimp edge of each stick.
Transfer sticks to a parchment lined baking sheet, about 1 inch apart.
Brush each stick with remaining egg wash and sprinkle with sea salt and cracked black pepper.
Bake hand pie sticks in the oven for 20 to 25 minutes or golden brown and cooked through.
Allow savory hand pie sticks to cool, about 15 minutes, before serving.
