Preheat the oven to 350 degrees, and spray a large baking sheet with olive oil spray.
In a large mixing bowl, season the chicken with the fennel, garlic, onion, red pepper, salt, and black pepper. Use a wooden spoon to stir together until evenly combined.
Next, add the cooked quinoa, green onions, and goat cheese. Stir again, until everything is evenly combined.
Use a 1 tbsp measuring spoon, and scoop out a heaping tbsp of the mixture into your hand. Use the palm of your hands to roll the mixture into small balls, repeating with the rest of the batter.
Place the balls on the baking sheet, and lightly spray the top of them with cooking spray. This step will help them brown on the top.
Bake for 20-25 minutes, until golden brown on top and cooked through.
