Pre-heat the oven to 325 degrees.
In a medium mixing bowl, toss all of the ingredients together until well combined.
Spread the mixture out onto a large, unlined baking sheet and bake for 10 minutes at 325 degrees. Take the sheet pan out, stir the mixture around, and bake another 10 minutes until the nuts are fragrant and lightly toasted.
Leave the trail mix to cool completely before touching it. The maple syrup will cool and harden, sticking the seasonings to the nuts. Once the trail mix has cooled, you can store it in an airtight container in the pantry for up to 2 months.
