I found some...

• 1 cup cooked mashed sweet potatoes
• 1 teaspoon vanilla extract
• 1/2 stick melted margarine
• 1/2 cup white sugar
• 1/2 cup dark brown sugar
• 1/4 cup egg substitute
• 1 dash salt
• 1 dash each cinnamon and nutmeg
• 1 unbaked pie crust

Preheat oven to 400. Mix together sweet potatoes, extract, margarine, white and brown sugars, egg substitute, salt, cinnamon, and nutmeg. Blend well. Pour into pie crust and bake 12 minutes at 400. Reduce oven temperature to 350 and bake until done.
