Preheat oven to 350 degrees Fahrenheit and line a large, rimmed baking sheet with parchment paper. In a large mixing bowl, combine the oats, nuts and/or seeds, salt and cinnamon. Stir thoroughly to combine.Pour in the oil, maple syrup and/or honey and vanilla. Mix well, until every oat and nut is lightly coated. Pour the granola onto your prepared pan and use a large spoon to spread it in an even layer. Bake until golden, about 21 to 23 minutes, stirring halfway. The granola will further crisp up as it cools.Let the granola cool completely, undisturbed, before adding dried fruit (and chocolate chips, if using). Store the granola in an airtight container at room temperature for 1 to 2 weeks, or in a sealed freezer bag in the freezer for up to 3 months.
