Preheat oven to 250 degrees F.
In a large bowl, combine the oats,
nuts, and brown sugar and spice.
In a separate bowl, combine maple syrup, oil, and salt. Combine both mixtures and pour onto 2 sheet pans. Cook for 1 hour and 15 minutes, stirring every 15 minutes to achieve an even color.
Remove from oven and transfer into a large bowl. Add raisins and mix until evenly distributed.
