Combine the oats, quinoa, pistachios, pecans, pumpkin seeds, chia seeds, cinnamon, salt, and vanilla in a large bowl and stir until combined.
Using a liquid measuring cup, pour oil and sweetener over top and stir once more until dry mixture is completely coated.
Add mixture to a baking sheet lined with parchment paper.
Bake for 25-30 minutes or until slightly browned. Turn pan halfway through to ensure even cooking. If like your granola more chunky, do not stir the granola and let it completely cool before break apart. For less chunky granola, stir granola throughout the baking process.
