Bring water to a boil in a large pot or dutch oven of at least a 5-quart capacity.

Stir in steel cut oats.  Reduce heat to low and simmer, uncovered, while stirring occasionally for 20 to 25 minutes or until oats reach desired consistency.

While heating water for oats, place sliced apples in a large pan over medium-high heat.  Add 1 1/2 cups water and sprinkle evenly with cinnamon.  Stir to combine.  When mixture begins to simmer, reduce heat to medium-low.  Add raisins and simmer for about five minutes.

When apples begin to soften, add sliced peaches.  Stir to combine.  Simmer for an additional 4 to 5 minutes or until all fruit is softened and the juice has thickened.

Add the cooked fruit to the prepared oatmeal and stir to combine.  Serve immediately.  Delicious topped with granola and fresh berries.

Store unused oatmeal in an airtight container in the refrigerator for up to five days.  Reheat individual servings on the stovetop or in the microwave.
