Combine the rolled oats, vegan vanilla protein powder, chia seeds, ground flaxseed, and a pinch of kosher salt in a medium jar or container and mix well.
Stir in the peanut butter, jelly, vanilla extract, unsweetened almond milk, and thick vegan or plain Greek yogurt until all ingredients are thoroughly blended.
Seal the container with a lid and refrigerate for a minimum of 3 hours or overnight to allow the oats to soak and flavors to meld.
In the morning, if the mixture is too thick for your liking, add a little water or extra almond milk to loosen the consistency.
Optionally, garnish with some chopped fruit, peanuts, or an extra dollop of peanut butter and jelly before serving for added texture and flavor. Enjoy your nutritious and tasty breakfast!
