Place the chicken breast between two sheets of parchment paper and pound with a meat mallet to an even 1/2-inch thickness.
In a shallow bowl, whisk the egg white until it becomes light and frothy.
In a second shallow bowl, combine the almond flour, grated parmesan, garlic powder, dried oregano, sea salt, and black pepper.
Dip the chicken breast into the egg white, allowing any excess to drip off, then dredge it in the almond flour mixture, pressing firmly to ensure a thick crust.
Heat the extra virgin olive oil in a large oven-safe skillet over medium heat.
Sear the chicken for 3-4 minutes per side until the crust is golden and the chicken is nearly cooked through.
Spoon the marinara sauce over the chicken and top with the shredded mozzarella cheese.
Place the skillet under the oven broiler for 2-3 minutes until the cheese is melted, bubbly, and slightly browned.
While the chicken rests, lightly sauté the zucchini noodles in a separate pan for 2 minutes until just tender, then serve the chicken on top garnished with fresh basil.
