Preheat your oven to 400°.
In a large bowl add ground chicken, egg, Parmesan, breadcrumbs, garlic powder and salt. Mix with hands to combine.
Spread mixture on a large parchment lined sheet pan and spread into a large round circle shape.
Sprinkle with more breadcrumbs and spray with oil.
Bake for 30 minutes.
Remove and top with marinara, a sprinkle of Parmesan, mozzarella and oregano.
Bake for an additional 5-7 minutes and broil for the last few minutes to get the cheese nice and bubbly.
Garnish with fresh basil and cut into slices.
