Preheat oven to 400°F.
In a large bowl, mix together the ground chicken, Italian seasoning, garlic powder, salt, and pepper until well combined.
Press the chicken mixture into a 12-inch circle on a parchment-lined baking sheet.
Bake for 20-25 minutes, until the chicken crust is cooked through and lightly browned.
Remove the crust from the oven and top with the shredded mozzarella cheese, pizza sauce, and your favorite toppings.
Return the pizza to the oven and bake for an additional 10-15 minutes, until the cheese is melted and bubbly.
Slice and serve hot.
