Slice apples uniformly into a pyrex baking dish.
Toss with lemon juice, cinnamon, vanilla extract.
Combine in a food processor to make the topping:
1 C rolled oats
1/2 C pitted dates
1/4 - 1/3 C coconut oil
1/4 - 1/2 C pecans
1/8- 1/4 tea salt
Sprinkle topping over apple mixture in pan.
Bake at 350 degrees for 30 minutes, or until soft inside and slightly crispy on top. Or it would probably be good raw just as is without baking.
