1. Rinse the Millet: Place the uncooked millet in a fine-mesh sieve and rinse it thoroughly under cold running water for about 30 seconds. This helps remove any bitterness and ensures a cleaner flavor.

2. Combine Ingredients in a Pot: In a medium-sized saucepan, combine the rinsed millet, water or almond milk, diced apple, grated fresh ginger, ground cinnamon, ground nutmeg, and a pinch of salt. Stir everything together gently.

3. Bring to a Boil: Place the saucepan over medium-high heat and bring the mixture to a rolling boil. Keep an eye on it to prevent it from boiling over.

4. Simmer and Cook: Once boiling, reduce the heat to low, cover the pot with a tight-fitting lid, and let it simmer for 15-20 minutes. The millet is done when all the liquid has been absorbed and the grains are tender and fluffy.

5. Stir in Mashed Banana: Remove the pot from the heat. Stir in the mashed ripe banana. The residual heat will warm the banana through and help to naturally sweeten and thicken the millet.

6. Fluff and Serve: Let the millet sit, covered, for another 5 minutes to allow it to steam and become even fluffier. Then, gently fluff it with a fork.

7. Add Toppings and Enjoy: Divide the warm millet into serving bowls. Add your favorite toppings like chopped nuts, a drizzle of maple syrup, extra sliced banana, or a sprinkle of chia seeds, and serve immediately.
