Preheat your oven to 375°F and lightly grease a small oven-safe baking dish with the coconut oil.
In a skillet over medium heat, brown the ground pork until fully cooked through, then drain any excess liquid or fat.
Core and dice the apple into small pieces, then add them to the skillet with the pork along with the cinnamon, sea salt, and water.
Simmer the pork and apple mixture for 3 to 5 minutes until the apples have softened slightly.
In a separate small bowl, whisk the egg and maple syrup together, then stir in the rolled oats and chopped pecans until well combined.
Transfer the pork and apple mixture into the prepared baking dish and spread it into an even layer.
Spoon the oat and egg mixture over the top, pressing down gently to ensure it covers the pork.
Bake for 15 to 18 minutes until the crumble topping is set and the edges are bubbling.
