Line a large, rimmed baking sheet with parchment paper and lightly grease the parchment with nonstick cooking spray.
in a bowl (for the microwave) or in a saucepan (for the stove), combine the peanut butter, honey, vanilla, coconut oil and salt. Melt over low heat until the ingredients are smooth and well-combined.
In a large bowl, toss together the nuts and oats.
Pour the peanut butter mixture over the dry ingredients, stirring with a wooden spoon until evenly coated - the overall granola mixture won't be overly wet once combined so don't fret.
Spread the granola into an even layer on the prepared baking sheet.
Bake for 15-20 minutes, tossing once or twice during the baking time.
Let the granola cool on the baking sheet (it will get crispier as it cools). If desired, stir the mini chocolate chips into the granola after it has cooled completely. Store in an airtight container at room temperature for up to two weeks.
Notes
Adaptable: you can leave the nuts out completely, if desired (same with the chocolate chips) or change it up and add in other ingredients you may enjoy like cacao nibs, other nuts or seeds, and whatever else your heart desires. Just try to keep the general ingredient amounts the same.
