Line a rimmed baking sheet with parchment paper or foil. Set aside. Preheat oven to 350 degrees F. In a bowl, combine ground chicken, egg, bread crumbs, hot sauce, kosher salt, pepper and blue cheese. It's easiest to do this with your hands. Using a cookie scoop, portion out 18 even meatballs. Place on prepared baking sheet. Bake for 15 to 20 minutes, until cooked through.
