Preheat your oven to 400°F (200°C). Line a baking sheet or pizza stone with parchment paper or aluminum foil and lightly grease it with olive oil.
In a mixing bowl, combine the ground chicken, grated Parmesan cheese, dried oregano, garlic powder, salt, and pepper. Mix until well combined.
Transfer the chicken mixture to the prepared baking sheet or pizza stone and spread it out evenly to form a round or rectangular crust, about 1/4 inch thick.
Bake the chicken crust in the preheated oven for 15 minutes, or until cooked through and slightly golden brown around the edges.
Remove the chicken crust from the oven and spread the marinara sauce evenly over the surface.
Arrange the sliced or shredded mozzarella cheese over the marinara sauce, followed by the thinly sliced tomatoes.
Return the pizza to the oven and bake for an additional 10 minutes, or until the cheese is melted and bubbly.
Once the pizza is cooked, remove it from the oven and sprinkle torn fresh basil leaves over the top.
Optional: Drizzle balsamic glaze over the pizza for added flavor and presentation.
