Preheat oven to 400 degrees.

Use a rolling pin to flatten pre-made pie crust into a large circle, about 8-10 inches in diameter. Set aside.

Remove core and seeds from Asian pear and slice into thin half-circle slices.

In a bowl, mix together melted butter, brown sugar, cinnamon, and vanilla extract. Add in sliced pears and minced ginger to butter mixture.

Place coated pears into center of pie crust, leaving a 2 inch edge of crust.

Fold in crust edges. Brush entire galette with whisked egg wash.

Bake for 30 minutes.
