Preheat your oven to 400°F (200°C) and line a baking sheet with parchment paper.
Place the chicken breast between two sheets of plastic wrap and pound it to an even half-inch thickness.
Season both sides of the chicken with sea salt and black pepper.
In a shallow bowl, whisk the egg white until slightly frothy.
In a second shallow bowl, combine the panko breadcrumbs, almond flour, garlic powder, and dried oregano.
Dip the chicken breast into the egg white, letting the excess drip off, then press it firmly into the breadcrumb mixture until fully coated.
Place the coated chicken on the prepared baking sheet and drizzle evenly with olive oil.
Bake for 15 minutes, then remove from the oven.
Spoon the marinara sauce over the chicken and top with the mozzarella cheese.
Return to the oven for 5-7 minutes, or until the cheese is melted and bubbly.
While the chicken finishes, lightly sauté the zucchini noodles in a pan for 2-3 minutes until just tender.
Serve the crispy chicken over the zucchini noodles and garnish with the parmesan cheese.
