Preheat your oven to 350 degrees. Line a baking tray with parchment and set aside.
Whisk together the coconut, sugar, flour, salt and vanilla.
Beat your egg whites in a separate bowl until stiff peeks form. Fold into your batter. Drop by teaspoon full onto your prepared sheet and bake 15-18 minutes, or until lightly browned on the edges.
Dip or drizzle in chocolate if desired.
