Preheat oven to 375°F (190°C).

In a large bowl, cream together butter-flavored Crisco, sugar, and brown sugar until light and fluffy.

Stir in vanilla extract.

Beat in the egg until well combined.

In a separate bowl, whisk together flour, salt, and baking soda.

Gradually add the dry ingredients to the wet ingredients, mixing until just combined.

Stir in the coconut and potato flakes.

Drop by rounded tablespoons onto ungreased baking sheets.

Bake for 10-12 minutes, or until golden brown.

Let cool on baking sheets for a few minutes before transferring to a wire rack to cool completely.
