In a medium bowl, beat together egg substitute, pumpkin, sugar, spices, and evaporated milk. Pour into the prepared pie crust. Bake at 400 for 15 minutes, then lower oven to 325 and bake for another 35-45 minutes, until edges of pumpkin are set but center is still just a little jiggly. Remove from the oven and let cool for 2 hours before serving or refrigerating. Serves 6 to 8, depending how you cut it. Enjoy!
