Preheat your oven to 425°F (220°C).
In a large bowl, combine ground chicken, mozzarella cheese, Parmesan cheese, egg, Italian seasoning, salt, and pepper.
Mix until well combined.
Spread the mixture onto a parchment-lined baking sheet, forming a pizza crust.
Bake the crust for 15 minutes or until golden brown.
Remove from the oven and spread pizza sauce evenly over the crust.
Add your desired toppings over the sauce.
Return the pizza to the oven and bake for an additional 10 minutes.
Once the cheese is bubbly and toppings are cooked, remove from oven.
Let it cool for a few minutes, slice, and serve.
