Preheat your oven to 400°F and line a rimmed baking sheet with parchment paper to prevent sticking.
In a medium mixing bowl, combine the ground chicken, liquid egg whites, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Place the chicken mixture onto the prepared baking sheet and press it into a thin, even circle about 1/4-inch thick.
Bake the chicken crust for 15 to 20 minutes until the edges are golden brown and the center is firm to the touch.
Remove the crust from the oven and spread the tomato puree evenly across the surface, leaving a small border for the crust.
Tear or slice the fresh mozzarella and distribute it over the sauce.
Return the pizza to the oven for another 5 to 7 minutes until the mozzarella is melted and bubbly.
Remove from the oven, top with fresh basil leaves, and let it rest for 2 minutes before slicing.
