In a bowl, mix the gelatin powder and boiling water, until the powder is dissolved.
Fill up a 1 cup measuring cup with about 1/2 cup of ice and then fill the cup up to the 1 cup mark with water. Add to the hot water/jello mix and stir until the ice has melted.
Fold in 2/3 of the Cool Whip into the Jello mixture and mix gently until smooth.
Add about 1/2 cup of the strawberry slices into the mixture, mixing gently.
Pour into the pie crust and refrigerate for at least 4 hours or freeze if you want to serve a frozen pie.
When ready to serve, cover with the remaining Cool Whip and garnish with the remaining strawberries.
