To a small mixing bowl add yogurt, oats, milk, and chia seeds then stir to combine.
To layer the overnight oats in mason jars: Let oat mixture sit and thicken for 5 minutes then scoop ½ cup into the bottom of each mason jar. Top with ½ cup fruit/berries then repeat layers. Top with sliced almonds then screw on the lids.
Alternatively, divide the oat mixture between the two storage containers, top each with half the fruit/berries and sliced almonds, and then cover.
Store high protein overnight oats in the refrigerator for at least 1 hour before eating. Can be refrigerated for 3-4 days.
