Preheating oven to 250 degrees.

In a large bowl, combine the oats, nuts, coconut, and brown sugar, then set aside.

In a separate bowl, combine maple syrup, oil, and salt. 

Pour the liquid over the oat mixture and stir well to combine.

Spread granola mixture onto a sheet pan and cook for 1 hour and 15 minutes, stirring halfway through to achieve an even color.

When finished baking, remove from the oven, and transfer to a large bowl. Add craisins/raisins (if using) and mix until evenly distributed.
