In a food processor Pulse Almonds intermittently until they are chopped in large pieces.
Add Hazelnuts into food processor along with the rough chopped Almonds and pulse until they are in large pieces
Add Pecans into food processor along with the almond and hazelnuts (you add the pecans last as they are the softest nut) and pulse again until they are in large pieces.
Add sunflower seeds, sweetener, and flaxseed meal to the nut mixture in food processor and pulse until everything is combined.
In a separate bowl, whisk the egg white and melted butter together and pour over the mixture and stir until fully combined.
Pour the mixture out onto a large parchment-lined baking sheet and press to form a large triangle.
Bake at 325 degrees for 15-18 minutes until lightly browned, being careful not to burn the edges.
Once removed from the oven let it cool completely. The cereal will be soft when removed from the oven but will crisp up as it cools.
Break apart with your hands into bite-sized pieces. Store in a sealable container.
