Preheat oven to 400°F and line a baking sheet with parchment paper.
Pound the chicken breast to an even thickness and pat dry with a paper towel.
In a shallow bowl, whisk the egg white until frothy.
In a separate bowl, combine almond flour, parmesan, garlic powder, oregano, salt, and pepper.
Dip chicken into the egg white, then press into the almond flour mixture until fully coated.
Place chicken on the baking sheet, drizzle with 1 tsp olive oil, and bake for 15 minutes.
Remove from oven, top with marinara and mozzarella, then broil for 2 minutes until the cheese is bubbly and golden.
Sauté spiralized zucchini in a pan with the remaining 1 tsp olive oil for 2 minutes until just tender.
Serve the crispy chicken over the zucchini noodles and enjoy immediately.
