Preheat your broiler and spray a baking sheet with cooking spray. Set aside

Spray a small, non-stick, frying pan with cooking spray and heat on high.

Once hot, turn down the heat to medium/low and slowly pour 1/2 cup of liquid egg whites in, covering with a tight fitting lid. Cook until the top of the whites are just set and slightly bubbly (about 2-3 minutes).

Remove the lid, carefully flip the egg whites and cook for an additional 2-3 minutes, or until the “tortilla” is cooked.

Slide onto a plate and repeat with the remaining 4 egg (1/2 cup) of egg whites.

Transfer each “crust” to the prepared baking sheet and sprinkle each with 1 tablespoon of grated parmesan cheese, 1/4 teaspoon of Italian seasoning, and a pinch of salt. Spreading the mixture out to cover each crust.

Adjust your oven rack to the very top position and place the broil the crusts until golden brown and crunchy, about 7-10 minutes. They burn easily so watch them closely!

Take the crusts out of the oven and top with pizza sauce, toppings and cheese.

Broil for an additional 2-3 minutes until the cheese is melted and golden.

Serve immediately.
