Preheat oven to 350 degrees F. In a large bowl, toss nuts with olive oil and 2 tbsp maple syrup until well coated. In a small bowl, combine coconut sugar, sea salt, cinnamon, nutmeg, and cayenne pepper and mix well. Reserve about 1/2 tbsp of mixture for after roasting. Sprinkle remaining spices over nuts and toss to coat. Spread seasoned nuts on a baking sheet and bake for 15-18 minutes, stirring halfway through.
