Preheat oven to 325℉. Line two large baking sheets with parchment paper.
Place the oats, pumpkin seeds, sliced almonds, and coconut in a large bowl. Add the ground ginger, cardamom, and salt. Stir to combine. Add the olive oil and maple syrup and stir very well so that the oat mixture is coated with the oil and syrup.
Spread the granola evenly on the baking sheets. Place in the oven and bake for about 22 minutes, depending on how well-cooked you like your granola. Remove from the oven and let the granola cool completely on the pans, about 30 minutes. It will crisp up a bit more as it sets.
Store the granola in an airtight container at room temperature.
