In a bowl, mix cornstarch and sugar with a dash of salt.

In a saucepan, pour boiling water over the sugar and cornstarch mixture.

Cook the mixture over medium heat until it becomes clear and slightly thickened.

Remove from heat and let the mixture cool slightly.

Fold in the strawberry Jell-O gelatin dessert and red food coloring until well combined.

Allow the gelatin mixture to cool completely.

Arrange sliced strawberries in the prebaked pie shell.

Pour the cooled sugar and gelatin mixture evenly over the strawberries.

Refrigerate the pie for at least one hour, or until the filling is firm, before serving.
