Begin by peeling your medium ripe banana. Slice it in half. You can mash one half and slice the other for topping later.
In a mixing bowl, combine your quick oats, liquid Orgain's vanilla protein shake, and egg whites. Stir well until all ingredients are fully incorporated.
Mix in the mashed half of the banana and the maple syrup. The banana will add natural sweetness, while the maple syrup enhances the flavor.
Transfer your oat mixture to a saucepan and cook over medium heat. Stir frequently to prevent sticking and ensure even cooking. You can also microwave the mixture in a microwave-safe bowl for about 1-2 minutes, stirring halfway through.
Once your oats have thickened and reached your desired consistency, remove them from the heat. Stir in the chopped walnuts for that delightful crunch.
Spoon your Banana Nut Protein Oats into a serving bowl. Top with the sliced half of your banana and additional walnuts if desired. Enjoy your hearty and nutritious breakfast!
