Combine the oats and water in a pot on the stove and turn on heat to medium high. Bring water to a simmer, stirring occasionally.
Once the water is boiling and the oats start absorbing liquid, reduce the temperature to low. Let cook until water is absorbed.
Crack the egg into the oatmeal and quickly whisk into the oats, using a spatula. Stir continually for approximately 30-60 seconds, or until the egg is fully cooked (you should not see any raw egg left in the oats). The spatula and continual whisking, along with a low temperature, are key to avoiding any clumps of scrambled egg.
Season the oatmeal with a pinch of salt, a pinch of ginger, and a generous pinch of cinnamon.
Turn off the stove and serve the oatmeal in a bowl. Top with peanut butter (or nut butter of choice) and fruit.
You can easily scale this recipes for 2, 3, or 4 servings. You can also cook the oatmeal in advance, store in the fridge, and then reheat and serve with nut butter and fruit.
