Preheat oven to 350 degrees.
Spread nuts over baking sheet evenly. Roast in oven for 5-10 minutes, or until lightly toasted. Watch closely! The smaller the nut or nut pieces the more quickly they will brown. My almond pepita mixture only took 5 minutes. Remove from oven and dump onto plate to stop the toasting process.
In a medium bowl, place old fashioned oats, chia seeds, and nuts - once they are slightly cooled.
In a small bowl combine remaining ingredients, maple syrup through salt. Mix well.
Pour maple syrup mixture over oat and nut mixture. Stir well. Let sit for a few minutes.
Spread onto baking sheet lined with parchment paper or foil. The more thinly you spread, the better it will turn out.
Reduce oven to 325 degrees. Bake for 25-30 minutes. Flip with a spatula, breaking up large chunks. Bake another 10-20 minutes, or until all pieces are dried out and brown. Note: after baking, as it sits and cools, granola will dry out further so if some larger pieces still feel a little spongy, it's good.
