1. In a medium saucepan, bring the water and salt to a boil. Stir in the oats and raisins, reduce the heat to low and simmer to desired doneness and texture (5-7 minutes).
2. While oats cook, toast nuts in a dry skillet over medium-high, stirring frequently, until golden and fragrant (3-5 minutes).
3. Stir vanilla, cinnamon, and nutmeg into cooked oatmeal. Serve oatmeal topped with toasted nuts, brown sugar, and milk.
