Tuna Melt Chaffle Sandwich

What is a Chaffle?
A chaffle is a “cheese waffle”- it’s a great substitute for bread in any keto sandwich! I love chaffles because they are incredibly versatile and delicious. All you need to make them is a Mini Waffle Maker! You can use chaffles instead of bread, like on this Keto Turkey Club Sandwich, Chicken Bacon Ranch Chaffle or this Jalapeno Popper Burger. You can also make them for breakfast, like these Bacon Cheddar Chaffles, Sausage Jalapeno Chaffles or a Breakfast Chaffle Bowl.
Sweet chaffles are delicious, too! Some of my favorites are Cream Cheese Chaffles, Blueberry Chaffles or Cinnamon Roll Chaffles. Pepperoni Pizza Chaffles, Keto BBQ Stacks or Keto Chili Cheese Chaffles are some of my go-to recipes for a keto lunch. If you have a Waffle Bowl Maker, you can prepare a Chaffle Bowl to make these Taco Chaffle Bowls or a Keto Salad Bowl!
