Preheat your oven to 400°F and line a baking sheet with parchment paper for easy cleanup.
Slice the chicken breast into thin cutlets and pound them to an even half-inch thickness using a meat mallet.
In a shallow bowl, whisk the egg white until slightly frothy.
In a separate shallow bowl, combine the almond flour, grated parmesan, garlic powder, oregano, sea salt, and black pepper.
Dip each chicken cutlet into the egg white, letting the excess drip off, then press firmly into the almond flour mixture until evenly coated.
Place the coated chicken on the prepared baking sheet and lightly mist the tops with a touch of olive oil spray.
Bake for 12 to 15 minutes, or until the chicken is cooked through and the coating is crisp and golden.
Spoon the marinara sauce over each piece of chicken and sprinkle with the shredded mozzarella cheese.
Return the pan to the oven for 2 to 3 minutes until the cheese is melted and bubbly.
While the chicken finishes, spiralize the zucchini into noodles and sauté them in a pan with the olive oil for 3 minutes until just tender.
Serve the crispy chicken parmesan over the bed of warm zucchini noodles.
