Ff pie crust ( contains egg white )

Preheat the oven to 375°F (190°C).

Whisk the egg white in a bowl until it forms stiff peaks, approximately 2-3 minutes with an electric mixer or by hand.

Gently fold the cooked brown rice into the whipped egg white using a spatula, being careful to preserve the airiness of the egg white while thoroughly combining the mixture.

Transfer the mixture to a lightly greased 9-inch pie dish, pressing it firmly and evenly across the bottom and up the sides to form a crust.

Bake the crust in the preheated oven for 20-25 minutes until it is set and lightly golden on the edges.

Remove the crust from the oven and allow it to cool for a few minutes before filling with desired pie filling.
