Combine oats, nuts, flaxseed and salt in a large mixing bowl. Melt the honey in a small microwave safe bowl for 15-30 seconds until very runny. Add the honey and oil to the oat mixture and stir until evenly coated and combined.
Spread the granola mixture into an even layer on a parchment paper or silicone mat lined baking sheet. Bake at 300 F for 45-60 minutes until lightly golden and nearly dry to the touch.
Allow the granola to cool completely on the baking sheet in order to achieve an extra chunky result (the best!)
