One way to add egg/egg whites to oatmeal that will create a smooth, silky texture is:
-Cook your oatmail on stovetop like you mormally do
-Add milk or cream and other other condiments (salt, sugar, etc.)
-When the oatmeal is cooked, turn off the heat or take the pot away from the heat completely
-Stir in the egg (usually 1 whole egg or 2 egg white), and quickly stir it with a stirrer. Make sure the pot is away from the heat!
- Stir it fast enough and in a minute or so, it will see the "egg drop soup" effect with smooth strands of egg incorporated into the oatmeal!
