Preheat your oven to 350°F (175°C).
Core and slice the apples into ½-inch thick slices, keeping the skin on for added fiber and nutrients.
In a bowl, mix the apple slices with maple syrup or honey, cinnamon, nutmeg, vanilla extract, and a small pinch of salt.
Grease a baking dish with coconut oil or butter, then spread the apple mixture evenly in the dish.
Optional toppings: Sprinkle rolled oats and chopped nuts over the apples for added texture and nutrition.
Bake for 25-30 minutes, or until the apples are tender and bubbling.
Cool slightly before serving, and enjoy with a dollop of Greek yogurt or a spoonful of coconut whipped cream for extra creaminess.
