Add the oats and water to a pot. Heat up over medium heat. While coming to heat, break a banana into 1 inch pieces and add to the pot. Use the back of your spatula to mash the bananas into the oats.
While cooking, add vanilla and salt to taste. Allow to continue cooking until the oats have absorbed all the water.
Remove the pot from the heat and add in egg whites. Stir continuously to avoid scrambling the eggs. Keep on the heat until there is no visible egg whites and the oatmeal is thick and fluffy.
Serve immediately, adding garnishes and add-ins as desired. My personal go to is raspberries, chia seeds, flax seeds and cinnamon.
You may add maple syrup or some other sweetener to this recipe but I find it perfectly sweet as is. If you like a sweeter oatmeal like the kinds packaged in pouches, add in about ½ - 1 tablespoon of your liquid sweetener of choice.
