Put the oats, water, applesauce, cinnamon and salt into a saucepan. Start with 1½ cups water and add more if you like thinner oatmeal.
¾ cup of rolled oats (large flaked), 1½ cups water, 1 cup unsweetened applesauce, ½ tsp cinnamon, tiny pinch of salt
Simmer on low heat for about 5–7 minutes, stirring now and then, until the oats have absorbed most of the liquid.
Add the milk and simmer for another 2 minutes.
½ cup milk of choice
Let it sit for a few minutes (it thickens as it cools). Taste, and sweeten only if you want it sweeter (see notes).
Serve with your favorite toppings: caramelized apples (see notes), a spoonful of nut butter, Greek yogurt, granola or extra applesauce.
