Peel and slice the apples and put them in a bowl. Add cinnamon and sugar and mix well. Transfer the apple slices to a baking sheet lined with parchment paper and bake for 15-20 minutes. 5 minutes before removing the apples from the oven, add the walnuts.

In a small saucepan pour in the water or nut milk and bring to a boil, then add the oatmeal (I used rice milk and it turned out pretty well). Reduce the heat and stir continuously for about 5-7 minutes.

Turn off the heat and add honey (or other sweetener if desired).

Serve in a bowl and garnish each serving with slices of warm baked apple and walnuts.
