Preheat the oven to 375°F. Line a sheet pan with parchment paper or a silicone baking mat.
Add the almonds, pecans, coconut, and coconut oil to a food processor.
Pulse 20 times or to desired texture for granola.
Pulse in the egg whites.
Spread the mixture in an even layer on the lined sheet pan.
Bake for 14 to 16 minutes until fragrant and crisp.
Allow to cool and then break into bite-size pieces.
Store in an airtight container at room temperature for up to a week. For longer storage, refrigerate the granola.
Notes
The coconut adds sweetness without sugar. However, those who prefer a sweeter cereal may want to add in sweetener and/or vanilla to taste.A teaspoon or two of cinnamon can also be added for enhanced flavor.Other nuts and seeds can be substituted as well.
