In a saucepan, combine rolled oats, milk, and a pinch of salt. Bring to a gentle boil over medium heat, stirring occasionally.
In a small bowl, whisk together the egg, honey, and vanilla extract.
Once the oats have absorbed most of the milk (about 5-7 minutes), reduce the heat to low. Gradually whisk in the egg mixture, stirring constantly to avoid scrambling the egg.
Cook for another 2-3 minutes until the oatmeal thickens and becomes creamy.
Remove from heat and serve immediately. Top with fresh berries, sliced bananas, and chopped nuts for extra texture and flavor.
