Warm a small skillet over medium heat. Add the nuts and toast them, stirring frequently until they become fragrant, about 1 to 2 minutes.
Add the maple syrup and salt, stirring until the nuts are well coated with the maple syrup, about 1 minute more. Remove the skillet from the heat and spread the nut mixture onto a piece of parchment paper, letting it cool completely.
Once cooled, break up any of the larger pieces into smaller clusters. Set aside.
