Add the cold water, corn starch, and sugar to a small saucepan over medium heat. Stir frequently and bring the mixture to a boil. The mixture will thicken very quickly once it starts boiling.

Remove the saucepan from the heat and add the jello.

Combine the strawberries and the filling mixture in a medium bowl. Allow the strawberry mixture to cool completely in the refrigerator.

Fill the pie crust with the cool strawberry mixture to the top of the pie crust.

Enjoy!
