In a large mixing bowl, separate the egg yolk from the egg white. Whisk the yolk with milk, olive oil, cheese, fresh herbs, salt, and pepper until smooth. Gradually fold in sifted flour and baking powder until just combined.

In a separate bowl, beat the egg whites until stiff peaks form, about 3-5 minutes. Fold gently into the batter from Step 1.

Preheat your waffle iron and lightly grease it. Pour batter into the center and cook for about 4 minutes, or until golden brown and crispy.

Carefully remove waffles and let cool on a wire rack for a few minutes. Trim edges and slice into strips or pieces.

Layer chosen fillings on waffle pieces and add toppings like pesto for extra flavor.

Serve on an elegant platter and encourage guests to customize their own waffle creations.
