Possible tweaks:
-if you don't want to eat it cold, warm it up in the microwave
-If you don't have finely shredded coconut flakes, I suggest grinding regular unsweetened coconut flakes into smaller pieces in a food processor, or you could even grind them into flour in a coffee grinder for a smoother consistency. Do NOT substitute storebought coconut flour because it will soak up a lot more liquid.
-The protein powder is there to give a source of protein (duh) as well as to thicken the porridge. If you do not include the protein powder, make sure you eat an additional source of protein (Greek yogurt, bacon) with your breakfast. Also, your porridge will be slightly runnier than normal.
-If you don't have or do not like the texture of glucomannan (a natural thickening agent), here are some options: a) just leave the thickener out and eat the pudding runnier, b) decrease the liquid, c) substitute xanthan gum, and/or d) add some ground golden flax or chia seeds to help gel the porridge.
