In a bowl combine chicken, buffalo sauce, bleu cheese, onion flakes, dried parsley, and a ¼ cup of the shredded cheddar. Mix well.
On a baking sheet spread out the half bag of potato chips. Sprinkle ¼ cup of the shredded cheddar over the chips, followed by the chicken mixture and then the rest of the remaining shredded cheddar cheese. Bake for 5 minutes at 450 degrees.
Remove from oven and garnish with green onions. Serve and enjoy immediately.
