Dissolve Lime Gelatin (1 package) in boiling Water (1 cup). Let cool to room temperature.
Stir in Lime (2 teaspoon) and Lime Juice (1/2 cup).
Add Sweetened Condensed Milk (14 ounce) stirring until blended.
Chill mixture until slightly thickened, stirring occasionally.
In another bowl, combine Whipping Cream (1 pint) and Powdered Confectioners Sugar (1/4 cup) and mix until it forms stiff peaks.
Pour thickened gelatin mixture into a medium-sized bowl.
Fold in one-half of the sweetened whipped cream, saving the remainder for garnish.
Stir in Green Food Coloring (3 drop) into the gelatin mixture, if desired.
Pour gelatin mixture into cooled Vanilla Wafer Pie Crust (1).
Refrigerate until set for about 3 hours.
Remove from refrigerator and cut into 8 equally-sized wedges. Place a dollop of reserved sweetened whipped cream on the top of each pie wedge. Place the Lime (8 slice) on top of each of the dollops of whipped cream.
Serve immediately, or refrigerate until serving time. Enjoy!
