Preheat your oven to 350°F (175°C) and lightly grease a small oven-safe ramekin or baking dish.
In a medium mixing bowl, whisk together the non-fat Greek yogurt, egg whites, and vanilla extract until the mixture is smooth and well combined.
Add the rolled oats, hemp hearts, cinnamon, baking powder, and sea salt to the wet ingredients, stirring until the oats are fully submerged.
Gently fold in the fresh blueberries, being careful not to burst them.
Transfer the oatmeal mixture into the prepared baking dish and spread it into an even layer.
Roughly chop the pecans and sprinkle them evenly over the top of the oats.
Bake for 25 to 30 minutes, or until the center is set and the pecans are toasted and fragrant.
Allow the dish to cool for 5 minutes before serving to let the texture firm up.
