Preheat the oven to 325. Spray 2 rimmed cookie sheets with non-stick cooking spray.
In a small mixing bowl, whisk together the melted butter or oil,honey and vanilla.
In a larger mixing bowl, toss together the quick cooking oats, rolled oats, cinnamon, ginger and chopped nuts.
Pour the honey mixture over the oat mixture and mix together.
Spread the granola onto the prepared cooking sheets and press to cover the bottom. If there is a little empty space on the cookie sheet, that's okay. You just want the granola not to be too thick in places and even all around, so it cooks evenly.
Place in the preheated oven and bake for 10 minutes.
Then turn off the oven after 10 minutes and let the granola finish cooking as the oven cools down. It's ready to eat the next morning. Use a metal spatula to loosen and break the granola into chunks for serving.
Serve Overnight Granola with milk or yogurt and some fresh fruit.
