Add the chia seeds, almond milk, maple syrup, and vanilla extract to a bowl and stir well. Use a whisk to ensure there is no clumping. Cover and refrigerate for 15 minutes.
After 15 minutes, add berries, nuts, or any other topping you like and enjoy!
Notes
Make sure to stir the cereal well before refrigerating to prevent clumping.
You can make this Whole30 compliant by skipping the maple syrup.
