Preheat oven to 425ºF. Cream the pumpkin and sugar. Add salt, spices, and tofu, mix thoroughly. Pour mixture into pie shell and bake for 15 minutes. Lower heat to 350 F and bake for another 40 minutes. Chill and serve. Don't use the low fat tofu, then the pie tastes like it was made with tofu. This pie is soooo yummy, it will fool almost anyone. Top with non dairy topping and it will fool any pumpkin pie lover.
