Grab a large heat-safe bowl, combine oats, coconut, and pecan pieces (dry ingredients). Set aside.
In a medium pot on medium heat, combine brown sugar, honey, salt, cinnamon, vanilla, and coconut oil. Stir frequently as the ingredients begin to melt, forming a syrup (about five minutes).
Once thoroughly combined, carefully pour the newly-made syrup into the heat-safe bowl with the dry ingredients. Stir several times to coat (2-3 minutes).
After the syrup is worked into the dry ingredients, pour the granola onto a baking sheet and spread evenly.
Bake in the preheated oven for 15 minutes.
Remove the granola from the oven and stir, then place back in the oven for another 15-20 minutes (or until it achieves a golden brown color).
After the cooking time is complete, continue to stir the granola, removing it from the baking sheet once it has cooled. Maximum crunch is achieved after it cools. Do not over-bake the granola as it will still appear "chewy" when first removed from the oven.
