pro tip: when i make it, i only make two days worth at a time. but...i fill enough jars with the dry ingredients (oatmeal, chia seeds, stevia/raw sugar) in advance and keep them in the pantry with the lids screwed on. then, after my two days worth of fully prepared porridge is gone, all i have to do is add milk, yogurt, syrup, and blueberries to the jars and put them in the fridge. saves some prep time.
btw...you can make all sorts of combos of flavors of porridge. you could put cocoa in there, apple sauce and cinnamon, bananas, etc, etc. whatever you think tastes good.
