Shred zucchini, cheddar cheese and chop green onions. Combine in a mixing bowl.
Mix in flour and egg to make a zucchini type batter. It will be sticky! Make sure the ingredients are well mixed!
Form small patties with the zucchini batter and place in the basket of your air fryer. Wet hands to avoid sticking.
Air fry for 15 minutes, until golden brown and flipping half way. Eat with tzatziki sauce, ranch, or on it's own!
