Preheat the oven to 350°F (177°C). Place a silpat mat on a rimmed baking sheet, or spray a rimmed baking sheet with cooking spray.
In a large bowl, mix together the oats, seeds, dried fruit, coconut, cinnamon, and salt. In another bowl, combine the butter, oil, and honey. Pour the wet ingredients over the dry, stir to combine, and spread the mixture onto the prepared baking sheet.
Bake the granola for 20 minutes, until golden. Let cool for at least 15 minutes, then use clean hands to break the granola into pieces. Transfer to an airtight container (I like lidded glass jars). Granola will stay fresh for a week to 10 days.
Suggested serving size is ½ a cup
