In a small bowl, stir cereal with milk and let soak for 5 minutes.
In a separate large bowl, combine cereal mixture, turkey, egg, spinach, onion, garlic, cheese salt, pepper, and thyme. Mix just until combined, avoid over mixing to ensure meatballs will not be tough.
Form mixture into 1 1/2 inch balls and place on a parchment lined baking sheet. Brush meatballs with oil and bake for 20-25 minutes or until cooked through.
Notes
Serve these meatballs on their own or in your favourite sauce.
