Preheat your oven to 400°F and line a large baking sheet with parchment paper to prevent sticking.
In a medium mixing bowl, combine the ground chicken, egg, sea salt, black pepper, garlic powder, and dried oregano using a spatula or your hands until fully incorporated.
Transfer the chicken mixture to the prepared baking sheet and press it down into a thin, even circle approximately 8 inches in diameter.
Bake the chicken crust for 15 to 20 minutes until the edges are golden brown and the center is firm and fully cooked.
Remove the crust from the oven and spread the tomato puree evenly across the surface, leaving a small border for the crust.
Tear the fresh mozzarella into small bite-sized pieces and scatter them over the tomato sauce.
Return the pizza to the oven for an additional 5 to 7 minutes, or until the cheese is melted and just beginning to bubble.
Remove from the oven, drizzle with extra virgin olive oil, and garnish with fresh basil leaves before slicing into wedges.
