Preheat the waffle maker: Set your mini waffle maker to medium-high heat and allow it to heat for about 2-3 minutes until fully preheated and a light indicator shows it's ready.
Prepare the egg mixture: Crack the egg into a small bowl, add the shredded cheese and your desired seasonings, then whisk together until well combined and the cheese is evenly distributed throughout the egg.
Grease the waffle maker: Lightly brush or spray both sides of the waffle maker with cooking spray or a small amount of butter to prevent sticking and ensure maximum crispiness.
Pour and cook: Pour the egg mixture into the preheated waffle maker, close gently, and cook for about 3-4 minutes until the edges are golden brown and crispy and no liquid egg remains visible at the seams.
Remove and serve: Carefully open the waffle maker and use a fork or small spatula to gently remove the crispy waffle egg onto a plate, being careful as it will be hot.
