Preheat your oven to 400°F and line a small baking sheet with parchment paper.
Place the chicken breast between two sheets of plastic wrap and pound to an even half-inch thickness.
Season both sides of the chicken breast with sea salt and black pepper.
In a shallow dish, whisk the egg white until it becomes slightly frothy.
In a second shallow dish, combine the almond flour, grated parmesan, garlic powder, and dried oregano.
Dip the chicken breast into the egg white, allowing any excess to drip off, then press firmly into the almond flour mixture until evenly coated.
Place the breaded chicken on the prepared baking sheet and lightly drizzle with half of the olive oil.
Bake for 15 to 18 minutes, or until the chicken is cooked through and the crust is golden brown.
Spoon the marinara sauce over the chicken and top with the mozzarella cheese.
Return the chicken to the oven for 2 to 3 minutes until the cheese is melted and bubbling.
While the cheese melts, heat the remaining olive oil in a skillet over medium heat and sauté the zucchini noodles for 2 minutes until just tender.
Plate the zucchini noodles and top with the crispy chicken parmesan.
