Prepare your station by preheating the oven to 325°F (165°C) and lining a large baking sheet with parchment paper.
In a medium-sized bowl, combine the dry : chopped pecans, sunflower seeds, coconut flakes, and almond flour.
Stir well to ensure they are evenly distributed.
In a separate small bowl, lightly whisk the egg white until just frothy.
Stir in the granular erythritol, melted butter, vanilla extract, and liquid stevia until fully combined.
Pour this wet mixture over the nut and seed mixture.
Stir everything together until the dry are completely and evenly coated with the egg white mixture.
Spread the granola in a single, even layer on the prepared baking sheet.
Bake for 25 to 30 minutes, stirring every 10 minutes to prevent burning and ensure even toasting. The granola is done when it's a light golden brown.
Remove from the oven and allow the granola to cool completely on the baking sheet. It will crisp up significantly as it cools.
Once cool, break it into clusters and serve.
