Prepare granola: Line a baking sheet with parchment paper. In a large bowl combine cashews, oats, almond butter, maple syrup, coconut oil, flax seeds, cinnamon, nutmeg, ginger, coconut sugar, and sea salt. Spread in an even layer on baking tray. Bake for 20 minutes and remove from oven. Add roasted chickpeas and coconut flakes and bake for an additional 5-10 minutes, or until coconut flakes are lightly golden.
