Put chia seeds in a bowl or food storage container (at least 1 quart in capacity). Set aside.
Add vanilla, cinnamon, salt, and whey powder to the almond milk, and blend until combined.
Pour mixture over chia seeds, and stir.
Let pudding sit at room temperature or in the refrigerator for 20-30 minutes. If you can, stir every 10 minutes (this helps avoid clumps of chia seeds).
Refrigerate and enjoy!
Notes
A note about substitutions: You can substitute vanilla casein protein powder for the whey, but you will need more almond milk. I would not use vegan protein powders in this recipe because they would give a chalky consistency to the pudding.
