Prepare the Chicken Mixture: In a large mixing bowl, combine the shredded chicken, mozzarella cheese, Parmesan cheese, breadcrumbs, egg, garlic powder, onion powder, salt, and pepper. Stir until well combined.
Form the Fritters: Using your hands or a spoon, shape the chicken mixture into small patties or fritters, about 2-3 inches in diameter.
Heat the Oil: Heat the olive oil in a non-stick skillet or frying pan over medium heat.
Fry the Fritters: Carefully place the fritters in the hot oil, cooking in batches to avoid overcrowding. Fry for 3-4 minutes on each side or until golden brown and crispy.
Drain and Serve: Transfer the fritters to a plate lined with paper towels to drain excess oil. Garnish with chopped parsley and serve warm.
