1. In a medium saucepan set over medium-low heat, combine coconut milk, maple syrup, hazelnut butter, dates, and apple. Bring to a boil, stirring occasionally to prevent burning and ensure that everything is well combined. Reduce heat to low and cook for about 5 minutes, until dates and apple have softened.
2. Add cooked brown rice and nutmeg, stirring until all the ingredients are fully combined. Continue cooking for about 5 minutes, until rice is warm and soft. Serve immediately.
