Preheat the oven to 350 degrees and line a half-sheet pan with a silicone baking mat or parchment paper. In a large mixing bowl, combine the oats, nuts, salt, cinnamon and ground ginger. Stir thoroughly to combine. In a small saucepan, melt together the oil, honey and vanilla. Pour over dry ingredients & mix well. Evenly spread granola onto your prepared pan. Bake for 22 to 24 minutes, stirring halfway. The granola should be turning lightly golden. Let the granola cool completely before storing in a ziplock bag or airtight container.
