In a small bowl mix the egg, garlic powder, and cheddar Cheese.
Add the broccoli and chicken and mix well.
Add 1/2 of the batter into your mini waffle maker and cook for 4 minutes. If they are still a bit uncooked leave it cooking for another 2 minutes. Then cook the rest of the batter to make a second chaffle and then cook the third chaffle.
After cooking remove from the pan and let sit for 2 minutes.
