Turn the oven on to 400 degrees F.
Add everything minus the pie dough into a bowl and mix well and set aside.
Follow the preparation instructions on the box for the pie dough. Use a biscuit cutter, round cookie cutter, or just a regular ol' cup to cut circles in the dough. (see notes for more info)
Take a dough circle and place roughly 1 1/2 teaspoons of pumpkin mixture in the center. The amount of mixture depends on how big the circles are, but it shouldn't be that off.
Dip your finger in water and dampen the edges around the entire circle. Fold the dough over as if you were making an empanada or dumpling, and try to squeeze out whatever air is inside.
Fold edges over on each other to give the pasties a more rustic look. (see notes for more info)
Place on a parchment lined sheet tray and cut a slit on the top so air can vent out.
Once all the pasties are laid out on the tray, get an egg wash (one egg mixed with a splash of water) and brush it on the pasties.
Place in the oven for 15-17 minutes depending on your oven.
Remove and let cool on a cooling rack.
