Place your nuts and seeds (individually, one type at a time) in a food processor. Pulse until they've been chopped to a medium-fine texture, stopping before they turn into nut butter. Place the nuts and seeds into a large mixing bowl.
Add the remaining ingredients to your mixing bowl and use your hands to mix together thoroughly.
Line two baking sheets with parchment paper. Divide the granola mix evenly between the two pans in a single, flat layer.
Place in the oven and bake for 10 minutes. Remove from the oven and stir the granola. Rotate your pans when you place back in the oven. Cook for an additional 10-15 minutes, being careful not to burn the granola. (Note: It can quickly go from golden to burned within a minute, so keep an eye on it. It won't look any different when it's done baking and will still be soft - that's fine. It will harden once it cools.)
Remove from the oven and let cool for 30 minutes. Place in a sealed container and store for future use.
