You can use fresh fried chicken or frozen breaded chicken that you bake. If using frozen chicken, place pieces on a baking sheet and bake according to package instructions.
While chicken is baking, preheat your waffle iron, then in a large bowl, gently stir together waffle mix ingredients just until no powder is remaining.
Spray the hot waffle iron with butter. Pour batter until bottom iron plate is ¾ of the way covered then close the waffle iron. Wait 2 minutes then rotate. Wait another 2 minutes then open waffle iron. Waffles should be a golden brown. Remove carefully with a fork and plate. Top waffle with maple syrup to taste.
When chicken is cooked, place 2-3 pieces on top of the waffle. Spoon country gravy on top of chicken to taste. Top with green onions and serve warm.
