here's the basic recipe i use for my overnight oats.
1/2 cup almond milk
2 T protein powder of your choice
1 t chia seeds
i mix these together in a bowl, cover it up and pop it in the fridge. that's it! in the morning, it's thickened up and makes for a nice filling breakfast. i top mine with sliced bananas and seasonal berries and a drizzle of maple syrup or honey.
also, i use glass for just about everything, and i found this glass bowl at tj maxx for $3 so get on that.
