Soak the oats: Add oats to a medium mixing bowl. Pour over the boiling water and mix well with a fork. Let sit for a few minutes to soak up fully. Then fluff up with the fork.
Mash in the banana: Once the oats are soaked and fluffed, break one banana in half over top of the oats and mash with a fork. A few lumps are okay but you do want the texture to be quite smooth so don't be lazy.
Combine: Pour in the soy milk and then add the chia seeds. Then add the vanilla and a pinch of sea salt. Mix well and let sit for about 8 minutes, until the chia seeds have become swelled and jelly-like.
Assemble and serve: You can leave the oatmeal in the same bowl or transfer it to a pretty one. Slice the remaining banana into rounds and add them over top. Then sprinkle over the walnuts and add a drizzling of maple syrup. Enjoy!
