Preheat oven to 350°F. Prepare a 9-inch pie crust by either using a store-bought crust or making one from scratch. Set aside.

In a large bowl, combine shredded coconut, sugar, and salt. In a separate bowl, whisk egg whites and vanilla until frothy.

Add egg whites to the coconut mixture and stir until well combined. Mix in melted butter.

Pour the mixture into the prepared pie crust, spreading evenly.

Bake for 25-30 minutes until golden brown and set. Remove from oven and let cool.

While the pie is baking, melt chocolate chips in a microwave-safe bowl, stirring every 20 seconds until smooth.

Once cooled, drizzle melted chocolate over the top of the pie and garnish with toasted coconut if desired.
