Add oats, banana slices, cinnamon and sea salt to a pot. Add water/milk and stir to combine. Heat over medium-high heat for 6-7 minutes or until all the liquid has been absorbed. Be sure to stir the oats several times while cooking to make sure the banana slices melt into the oats.
Add egg whites into the oats and stir/whisk constantly. Stirring will keep the egg whites from cooking/scrambling and they will turn into a thick, fluffy consistency instead. This should take 1-2 minutes.
Once all the liquid is absorbed and the oatmeal is cooked through, place in a bowl and add your favorite toppings. I used peanut butter, granola, coconut and freeze-dried raspberries.
