Preheat your oven to 400°F/205°C.
In a large bowl, combine the chicken, egg, onion, celery, garlic, coconut flour, onion powder, paprika, salt and black pepper. Combine well.
Line a baking sheet with parchment paper.
Use the mix to form small meatballs, about 1 inch in diameter.
Form one-by-one and place each meatball on the baking sheet. Be sure to leave enough room between each ball so that they aren’t at risk of touching when cooking.
Transfer the baking tray to the oven. Cook for 30 minutes, or until cooked through.
When cooked, remove from the oven and coat in your choice of sauce.
Serve with your choice of side, and with extra sauce for dipping or coating.
