Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
In a large bowl, mix ground chicken, eggs, parmesan, garlic powder, Italian seasoning, salt, and pepper until fully combined.
Press the chicken mixture into a thin circle or rectangle on the baking sheet.
Bake for 25 minutes, or until golden and cooked through. Let it rest for 5 minutes.
Turn the oven up to 425°F (220°C). Spread pesto on the crust, then add mozzarella and cherry tomatoes.
Bake for another 10 minutes, until bubbly and melty.
Optional: broil for 1–2 minutes for extra crisp, but watch it closely.
Let it cool slightly, top with more fresh parmesan, prosciutto and basil, then slice and serve.
