Preheat the oven to 350°F.

Toss the apples in lemon juice, arrange in a 9-inch glass pie dish or square baking dish and sprinkle with cinnamon and nutmeg.

Combine the flour, almond pulp if using, oats and brown sugar in a small bowl. Add coconut oil and use a fork to work it evenly into the dry mixture until the topping looks crumbly. Sprinkle onto the fruit.

Bake for about 25 minutes until the topping is golden and the fruit is soft.
