Preheat your mini waffle maker for about 5 minutes on a medium setting.

In a small bowl, crack the egg and whip it vigorously until frothy, then add drained tuna, shredded cheese, and a pinch of salt.

Sprinkle a teaspoon of shredded cheese onto the bottom plate of the preheated waffle maker.

Spoon half of the tuna mixture onto the center of the waffle maker, spread it out, close the lid, and cook for about 4 minutes or until golden brown.

Carefully lift the first chaffle out using a fork or silicone spatula, and allow it to cool on a wire rack.

Repeat the cooking process with the remaining tuna mixture to create the second chaffle.

Allow your chaffles to cool slightly before serving them with a salad or dipping sauce.
