Mix and Pour mixture into prepared crust. Bake for 10 to15 minutes until set. Refrigerate for at least 3 hours before serving. Garnish with whipped cream and lime zest

Whipped Cream is a must to nuetralize the sourness of the filling. You can use 1 pie pan instead of small ones. You can buy pre made crust instead of making your own.
