In a medium saucepan, combine 2 cups water, 1 cup rolled oats, 1 teaspoon cinnamon, 1/4 teaspoon nutmeg, 1/8 teaspoon salt, and the 2 medium apples (diced into small pieces).

Place the saucepan over medium-high heat and bring the mixture to a gentle boil, stirring once or twice to prevent sticking.

Reduce the heat to medium-low and simmer, stirring occasionally, for about 5 minutes or until the oats are tender and the diced apples begin to soften.

Remove the saucepan from the heat and stir in 1/2 cup unsweetened applesauce, 2 tablespoons maple syrup, and 1 teaspoon vanilla extract until evenly combined.

Portion the oatmeal into bowls and, if desired, top with additional diced apple pieces and an extra drizzle of maple syrup.

Serve warm.
