Preheat oven to 350°F and line a large, rimmed baking sheet with parchment paper. In a large mixing bowl, combine the oats, nuts, pumpkin seeds, salt, and cinnamon. Stir to blend.
Pour in the oil, brown sugar, maple syrup and/or honey, orange zest and vanilla. Mix well, until every oat and nut are lightly coated. Spread out granola on a parchment-lined rimmed baking sheet and bake, tossing occasionally, until golden brown, 20–25 minutes (mixture will still look wet but will dry as it cools).
The granola will further crisp up as it cools-- Let granola cool on baking sheet, then break into clusters. Mix in cranberries.
