Place the 3 egg yolks in a small bowl. Slightly beat the eggs with a fork or whisk, then stir a small amount of the hot mixture into the beaten yolks, stirring constantly as you add the hot liquid. (This is called "tempering" the egg yolks so they slowly warm up; this prevents the eggs from cooking when added to the hot mixture). When the egg yolks are thoroughly combined with the small amount of hot mixture, stir the egg yolks into the saucepan containing the hot mixture. Cook for one minute, stirring constantly.
Pour the warm pie filling over the bananas. Refrigerate until ready to serve (at least 4 hours). When pie is completely chilled, serve with a dollop of whipped cream on top OR make and top with meringue made from the 3 remaining egg whites. Serve, and enjoy!
