Preheat the oven to 350 degrees F. Grease a pie pan and set it aside.
Remove the cores from the apples and pears and thinly slice. Add into a large mixing bowl and sprinkle with coconut sugar and lemon. Toss to combine.
In a separate mixing bowl, combine the oats, quinoa, coconut oil and syrup. Mix to combine. Add quinoa and mix again until mixture starts to hold together when you press it between two fingers. Sprinkle with cinnamon and mix until just combined.
Transfer fruit to the prepared pie plate. Cover with topping and bake on the center rack for 35 - 45 minutes until the fruit is bubbling and the topping has browned. If the topping is browning too quickly, simply cover with tin foil until the filling is done.
Serve immediately (or top with vanilla ice cream and maple syrup) and enjoy!
