Preheat your oven to 400°F (200°C) and line a large baking sheet with parchment paper.
In a medium mixing bowl, combine the ground chicken, egg, grated parmesan, garlic powder, dried oregano, sea salt, and black pepper until fully incorporated.
Place the chicken mixture onto the prepared baking sheet and press it down into a thin, even circle approximately 9 inches in diameter.
Bake the chicken crust for 18-20 minutes, or until the edges are golden brown and the center is firm.
Remove the crust from the oven and spread the tomato puree evenly across the surface, leaving a half-inch border for the crust.
Tear the fresh mozzarella into small pieces and distribute them evenly over the sauce.
Return the pizza to the oven and bake for an additional 5-7 minutes until the mozzarella is melted and bubbly.
Remove from the oven, top with fresh basil leaves, and let rest for 2 minutes before slicing.
