Preheat your oven to 300°F (150°C) and line a small baking sheet with parchment paper.
In a medium bowl, whisk the liquid egg whites until they become frothy and light.
Gently fold in the unflavored whey protein isolate, nutritional yeast, garlic powder, onion powder, smoked paprika, and sea salt until a thick paste forms.
Stir in the pumpkin seeds and hemp hearts until they are evenly distributed throughout the mixture.
Spread the mixture onto the prepared baking sheet in a very thin, even layer using a silicone spatula.
Bake for 15 to 20 minutes, or until the edges are golden brown and the center feels firm and dry to the touch.
Remove from the oven and let the granola cool completely on the pan to ensure it reaches maximum crispness.
Once fully cooled, break the sheet into small, loose clusters and serve immediately or store in an airtight container.
