Line a square baking dish (8x8 or 9x9 inch) with parchment paper along the bottom and sides, leaving extra on the sides for easy removal. Set aside.
Place the nuts in the bowl of a food processor and pulse 5-10 times times to gently chop the nuts. Be careful not to overmix, so there are still some chunks left.
1 cup raw pecan halves, 1 cup raw almonds, 1 cup raw cashews
Transfer the nuts to a large mixing bowl and stir in gluten free rolled oats, cinnamon, nutmeg, salt, and dried apples.
1 cup old fashioned rolled oats, 1 Tablespoon ground cinnamon, 1/4 teaspoon nutmeg, 1/2 teaspoon fine grain sea salt, 1 cup dried apples
In a separate small bowl, mix together the melted coconut oil, nut butter, maple syrup, and vanilla. Pour the wet mixture over the dry ingredients and stir with a rubber spatula to fully combine.

Pour the granola bar mixture into prepared pan and press down using the rubber spatula or your hands to tightly pack the bars.
