Bring the plant milk to a low simmer and then add the oats, flax, cinnamon, and salt. Reduce the heat to medium-low and stir it well to combine. Let it cook for 3-5 minutes or until it has thickened to your desired consistency and is hot all the way through.
Top with peanut butter, frozen wild blueberries, pumpkin seeds, chia seeds, hemp seeds, and walnuts.
I prefer frozen wild blueberries, pumpkin seeds, hemp seeds, and 1 tbsp of peanut butter on top of the oatmeal but feel free to use other fruit, nuts, or seeds.
You could use water instead of plant milk to make the oatmeal.
You could use almond butter instead of peanut butter.
