Preheat the oven to 325 degrees F.
Place the egg whites, sugar, cracker crumbs, pecans and coconut in a large bowl. Stir to combine. Pour the mixture into the unbaked pie shell and place in oven. Bake until glossy and set, 25 – 30 minutes.
The pie will be firm around the edges but moist and chewy in the center. Let the pie cool, then slice and serve with fresh fruit and whipped cream.
