If you have a double boiler, boil water, place chocolate chips in top sauce pan, and, stirring occasionally, melt the chocolate chips. If you don’t have a double boiler, boil 1-2 inches of water in a sauce pan. Place chocolate chips in a metal bowl or heat-proof glass bowl and place on top of the sauce pan. Stirring occasionally, melt the chocolate chips.
In a blender mix the tofu, sweetener, vanilla and dash of salt and the melted chocolate chips. Blend thoroughly. You may need to stop the blender and scrape down the sides a few times.
Pour the mixture into the pie crust and place the pie in the refrigerator for 1-2 hours. Serve on its own or with a dollop of soy whipped “cream.”
