1. Combine Oats and Liquid: In a medium saucepan, combine the rolled oats, water or milk, and salt. Bring the mixture to a gentle boil over medium heat, stirring occasionally.

2. Simmer the Oats: Once boiling, reduce the heat to low and let the oats simmer for 3-5 minutes, or until most of the liquid has been absorbed and the oats are starting to thicken. Stir periodically to prevent sticking.

3. Prepare Egg Whites: While the oats are simmering, measure out your liquid egg whites. Have your sweetener of choice ready as well.

4. Slowly Incorporate Egg Whites: This is the crucial step for a creamy texture. While continuously stirring the oats vigorously, slowly pour the liquid egg whites into the simmering oatmeal. Continue stirring for another 2-3 minutes. The egg whites will cook and integrate into the oats, making them incredibly fluffy and increasing their volume. Keep stirring until no visible liquid egg white remains and the oatmeal has thickened considerably.

5. Sweeten and Serve: Remove the saucepan from the heat. Stir in your chosen sweetener until fully combined. Taste and adjust sweetness as needed.

6. Add Toppings: Ladle the hot oatmeal into a bowl and add your favorite toppings. Fresh berries, sliced banana, a sprinkle of cinnamon, chopped nuts, or a drizzle of nut butter are all excellent choices. Serve immediately and enjoy your protein-packed breakfast!
