1. Preheat oven to 350ºF.
2. Toss the apples, the 1 tablespoon sugar, the starch, the cinnamon, and the lemon juice together in a mixing bowl.
3. Place the quinoa flakes or oats in a food processor fitted with the S blade, along with the flour, the 3 tablespoons of sugar, the cinnamon, and the sea salt. Pulse a few times (if you use oats, you want them to be a bit broken down). Drizzle in the coconut oil as you pulse a few times more, to form a crumbly topping. (If you need to add an extra tablespoon of coconut oil, feel free to do so.)
4. Transfer the apples to a 23-oz baking dish, and sprinkle them with the topping. Cover with foil and bake for 25 minutes. Uncover and allow to bake 10 minutes more, or until top is crispy. Serve.
