Preheat your mini waffle maker to medium heat for about 5 minutes.

In a small mixing bowl, crack the egg and whip it vigorously for about 30 seconds until fully combined.

Add the drained tuna, shredded cheese, and a pinch of salt to the whipped egg. Gently fold the ingredients together for about a minute.

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

Spoon half of your tuna mixture onto the hot waffle maker and close the lid. Cook for about 4 minutes, until golden brown.

Carefully remove the cooked chaffle using a fork. Repeat the cooking process with the remaining tuna mixture.

Let both chaffles rest for 1-2 minutes before serving.
