Preheat the oven to 200°C / 400°F. Line a large baking sheet with parchment paper.
In a large mixing bowl, combine 1 pound ground chicken, 2 cups shredded cheddar cheese, 1 teaspoon Italian seasoning, and 1 tablespoon olive oil. Mix until thoroughly combined.
Transfer the mixture to the lined baking sheet and press it into an even pizza-shaped crust about 1/2 inch thick.
Bake the crust in the preheated oven for 10–12 minutes, or until the crust is firm and no longer pink in the center.
Remove the crust from the oven and spread 1 cup tomato sauce evenly over it. Top with 4 small sliced mushrooms and 1/2 small chopped bell pepper, then sprinkle 1 cup shredded mozzarella cheese on top.
Return the pizza to the oven and bake 8–10 minutes more, or until the mozzarella has melted and the toppings are heated through.
Remove from the oven, let rest a couple of minutes, then slice and serve.
