In a large mixing bowl, combine the shredded chicken, shredded cheese, breadcrumbs, green onions, grated parmesan, garlic powder, onion powder, black pepper, and salt.
Add the beaten eggs to the mixture and stir until everything is well incorporated. The mixture should be sticky but manageable.
Refrigerate the mixture for about 30 minutes to make it easier to handle.
Heat about 1/4 inch of vegetable oil in a large skillet over medium heat.
Once the oil is hot, scoop about 2 tablespoons of the chicken mixture and form it into a patty. Place it carefully in the skillet. Repeat with the remaining mixture, being careful not to overcrowd the pan.
Fry the fritters for about 3-4 minutes on each side, or until they are golden brown and crispy.
Use a slotted spoon to transfer the fritters to a plate lined with paper towels to drain any excess oil.
Notes
Serve with ranch or garlic dipping sauce, garnished with freshly chopped parsley.
