Place oats in a medium size saucepan with coconut milk, vanilla, 2 Tablespoons of coconut sugar, chopped banana and sea salt. Bring to a boil and then reduce to medium heat. Cover and simmer, stirring constantly until oats are soft and creamy, about 15 minutes. Cooking time may vary depending on the oats you purchase, so also refer to cooking instructions on your oats. When finished cooking, oats should be creamy and thick, but still have some liquid around the edges of the saucepan.
