Directions:
Preheat your oven to 350°F (175°C).
In a blender, combine the margarine, eggs, sugar, salt, milk, vanilla extract, and all-purpose flour. Blend until smooth.
Pour the mixture into a greased 9-inch pie dish.
Bake in the preheated oven for about 45-50 minutes, or until the custard is set and the top is lightly browned.
Remove from the oven and let it cool to room temperature before serving.
I await your comments! Enjoy!
