Preheat your oven to 325°F (165°C) and line a small baking sheet with parchment paper for easy cleanup.
In a medium mixing bowl, combine the rolled oats, sliced almonds, pumpkin seeds, hemp hearts, ground cinnamon, and sea salt until well mixed.
In a separate small bowl, whisk the maple syrup, melted coconut oil, vanilla extract, and egg white together until the mixture is slightly frothy.
Pour the wet ingredients over the oat mixture and stir thoroughly, ensuring every oat and nut is evenly coated with the syrup and binder.
Spread the granola in a thin, even layer onto the prepared baking sheet to ensure even toasting.
Bake for 15 to 20 minutes, stirring the mixture halfway through to break up any large clusters and achieve a loose, golden-brown texture.
Remove the tray from the oven and allow the granola to cool completely on the pan; it will continue to crisp up as it reaches room temperature.
Place the Greek yogurt in a serving bowl and top with the cooled granola to enjoy a high-protein, crunchy breakfast.
