First, bake the pie crust according to the package instructions. It will most likely instruct you to poke holes in the bottom of the crust with a fork but if it doesn't, make sure to before baking to keep the crust from puffing up as it bakes without a filling. Set aside to cool.
In a saucepan, add water, sugar and cornstarch and whisk together until combined and smooth. Bring this mixture to a boil. Whisk for 2 minutes until the sauce is an opaque white color and thickened.

While the sauce is cooling, rinse and slice your strawberries. Pat them dry then add them into your baked pie crust and arrange into an even layer.
Once the strawberry gelatin filling has finished cooling, pour over the strawberries, making sure that all the pockets are filled and the sauce is settled in evenly.
Place the pie into the refrigerator to set up for at least 3 hours, preferably overnight.
Serve with cool whip or fresh whipped cream and enjoy!
