Roll dough onto floured surface to ⅛" thickness. Cut into 5 inch circles (use a bowl or mini tart tray for shape).
Spoon filling onto one half of each circle and sprinkle with cheese. Leave ¼ inch space of crust around the edge of the circle. Paint a little egg wash on edge of dough to help when closing. Fold over the other half and press ends together with fingers.
Lay each pocket onto a lined baking sheet. Slit two small lines in center with knife. Using a small pastry brush, apply egg wash onto top and sides of pie. Sprinkle pies with chia seeds.
