Preheat oven to 350°F (175°C). Line a baking sheet with parchment paper or lightly grease it and place on the middle oven rack.
In a large bowl, combine 3 cups shredded cooked chicken, 1/3 cup favorite hot sauce and 3 1/2 oz. fat-free cream cheese (softened). Mix until evenly combined.
Stir 1 cup shredded cheddar cheese and 1/4 cup chopped green onions into the chicken mixture. Set the mixture aside.
Set up three shallow bowls for coating: place 1/2 cup all-purpose flour in the first bowl (you won’t use all of it), put 2 lightly beaten eggs in the second bowl, and put 3 cups crushed Corn Flakes cereal in the third bowl.
Using a 1 1/2-inch scoop or a spoon, form the chicken mixture into 1 1/2-inch balls (about 30 total). For each ball: roll it lightly in the flour, dip it into the beaten eggs, then coat it in the crushed Corn Flakes. Place each coated ball on the prepared baking sheet, spacing them slightly apart.
Repeat step 5 until all the mixture is shaped and coated.
Bake the balls in the preheated oven for 20 to 25 minutes, until they are golden and heated through.
Let the bites cool on the baking sheet a few minutes, then serve warm. Serve with blue cheese or ranch dressing if desired.
