For a more indulgent mix (optional):
Cover a baking sheet with parchment and preheat your oven to 300°F.
Pour all the ingredients except the chocolate and dried fruit (if using) into a bowl. Mix until sugar starts to clump the oatmeal and nuts together.
Spread on the baking sheet and put in the oven. Every 10 minutes, stir and check how it is baking. Brown as desired. Remove from oven.
Finally, let cool. (This allows the granola to become crispy.)
If using chocolate and chopped fruit, add them now to finish.
Will keep in a jar or airtight container for 1 month.
