Bring water to boil in a medium-sized saucepan. Add salt, coriander, and oats, give it a stir then lower heat to maintain a slow simmer for a couple minutes.
Turn off the heat, give oats a stir, and cover the pan. Let sit for 5 - 15 minutes, depending on how much time you have and how firm or soft you like your oatmeal. Sweeten as you like and add toppings: toasted walnuts + dried blueberries or dried banana cut into rounds + cocoa nibs—play around and make your own breakfast dessert!
