Preheat your oven to 400 degrees and turn on your mini waffle maker.
In a small bowl, mix together the egg, almond flour, cheese and garlic powder until well combined.
Sprinkle the waffle iron with a little bit of cheese and then pour half of your batter in. Close the lid and cook until the automatic timer goes off; repeat for next chaffle.
Place the chaffles on a lined baking sheet and top with tuna salad (store bought or homemade with a mixture of tuna, mayo, pickles and/or celery).
Sprinkle more cheese over top and bake for about 5 minutes or until the tuna is warmed through and the cheese is melted.
