Add the mushrooms to a food processor and pulse until they reach a “ground meat” like consistency. Add to a bowl.
Add the garlic, ginger, oats and parsley to the food processor and pulse until the oats break up and reach a rough powder like consistency. Add this to the bowl.
Add in the all spice, cinnamon, apricots, onion, egg, turkey, salt and pepper and mix until well distributed.
Using a melon baller, remove the core and the stem and discard. Then hollow out the apple, reserving this apple filling and leaving at least 1/4 inch of apple around the edges.
Fill the hollowed out apple halves with the meat mixture and set aside.
