Combine sugar, cornstarch, and salt. Stir in milk and begin heating over medium heat, stirring constantly to prevent lumps from forming.

Bring to a boil and allow to boil for one minute while stirring.

Remove from heat. Stir in vanilla and banana flavorings. Dot with butter pieces and allow it to cool.

After the pudding has cooled down to room temperature, slice bananas and line bottom of a baked, cooled pie shell. This is the fun part where you get to add as many, or as few, bananas as you want to.

Pour the pudding into the pie shell on top of the bananas.

Pour egg whites into a clean, grease-free mixing bowl, and beat on low/medium speed using a stand mixer or rotary beaters for 1-2 minutes.

Increase the speed and beat until soft peaks form. Gradually add 1/4 cup of sugar, and continue beating until stiff peaks form.

Spread evenly on top of the pie, and place under the broiler to brown, watching carefully.

Depending on your broiler set up, this could take anywhere from 1-5 minutes. Just watch it really closely - the moment you turn your head, it'll burn! Take my word for it - I'm notorious for burning meringues.
