Cook the oatmeal or other grain of your choice (quinoa is nice too, a bit lighter in taste). Set aside and let cool.
Blend your protein and yogurt / nut milk as desired (you may like the thicker consistency, so use yogurt. I like more watery).
Portion out the oatmeal in 6 Mason jars (I just eyeball it. It gets too messy- and OCD-ish - to weigh it all!) Pour over top your protein blend
Pour in your healthy fats: of using oil for your healthy fats, use 2 tsp only. Nut butter is measured at 1 TBSP.
Top with ¼ cup mixed berries, and granola / flax / chai as you wish.
Store in the fridge. You can pop them in the microwave for 45 seconds or so (lid off), to warm it up before eating! Or you might enjoy it cold too!
