Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.

In a large mixing bowl, combine ground chicken, shredded mozzarella, grated Parmesan, egg, Italian herbs, garlic powder, salt, and pepper. Mix until blended.

Transfer the mixture onto the baking sheet and shape it into a round crust about 10-12 inches in diameter.

Bake the crust in the preheated oven for 20-25 minutes until golden brown and firm.

While the crust bakes, toss chopped romaine lettuce with Caesar dressing and additional grated Parmesan.

Once the crust has cooled slightly, top it with the Caesar salad mixture evenly.

Optionally, add cooked chicken pieces or crispy bacon bits and drizzle lightly with additional dressing before serving.
