Preheat the oven to 300˚F.
In a large bowl, mix together the oats, sugar, cinnamon and salt.
In a separate bowl, mix together the honey, coconut oil and vanilla. Pour in with the dry ingredients and mix until the oats are thoroughly coated.
On a baking sheet, spread the mixture in a thin, even layer. Bake for 15 minutes. Stir together and add the raisins. Bake for an additional 15 minutes.
Remove from the oven, and let cool for around 20 minutes. Store in an airtight container for up to 2 weeks.
