Preheat your waffle maker according to manufacturer's instructions, about 5 minutes.

In a mixing bowl, whisk the eggs until smooth and pale yellow, about 1-2 minutes.

Add the shredded cheese to the egg mixture and stir gently until evenly distributed.

Pour the batter into the center of the preheated waffle maker and spread evenly. Close the lid and cook for about 3-5 minutes.

Once cooked, carefully lift the chaffle out and let it cool slightly on a wire rack.

Serve plain or top with your choice of toppings like avocado or salsa.
