Preheat your oven to 350°F.
Line a large cookie sheet with parchment paper.
Stir the ground flax seed and warm water together and let the mixture sit for 5 minutes to thicken (should have the consistency of egg-yolks).
In a large bowl, mix together the seeds, nuts, oats, ground chili pepper and chili flakes.
Add the flax and water mixture, oil and maple syrup and stir well to ensure all dry ingredients are well coated.
Pour the granola onto the prepared baking sheet, sprinkle on the sea salt and bake until golden and dry (20 to 30 minutes). Keep an eye on the Granola as it bakes and stir every 7-10 minutes.
Cool completely on the baking sheet, then transfer to a lidded storage container.
