Put the chia seeds in a small bowl, and pour the protein shake over them. Stir well.
Let the chia mix sit for at least 30 minutes in the refrigerator. If you can, stir about every 10 minutes so the chia seeds don't clump up.
Once the chia pudding is ready, spoon some into each of two serving cups, then top with strawberries.
Spoon the remaining chia pudding into the cups, and top with blueberries.
Enjoy!
Notes
A note about substitutions: You can substitute vanilla casein protein powder for the whey, but you may need a little more water. I would not use vegan protein powders in this recipe because they would give a chalky consistency to the pudding.
