Bring the milk to boiling in a saucepan over the stove.
Add the oats, reduce the heat to medium-low, and stir while cooking until the milk is absorbed (about 5 minutes).
Add the salt, cinnamon, ginger, applesauce, and egg to the oats, and whisk for about 1 minute or until the egg is thoroughly combined and cooked (the texture should be creamy with no bits of egg yolk or white).
Add the apple and cook until soft. Remove from heat and stir in the chia seeds.
Serve and eat immediately, preferably with coffee.
