Preheat oven to 375. Line a cookie sheet with parchment paper. Set aside.
Place the walnuts, almonds and pepita seeds into a bowl and toss to combine. Add the melted butter and maple syrup and toss until all the nuts are wet. Add in the salt, cinnamon, ground ginger, ground cinnamon and nutmeg. Toss to coat. Once coated, pour onto the parchment lined sheet tray and spread evenly. Place in the oven and bake for 7 minutes. Remove and stir and then cook for 5 minutes more.
Remove for oven and allow to cool before placing them into a serving bowl or airtight container.
