Place the chicken breast between two sheets of parchment paper and pound with a meat mallet until it reaches an even half-inch thickness.
In a shallow bowl, whisk the egg white until it becomes slightly frothy.
In a separate shallow dish, combine the almond flour, grated parmesan cheese, garlic powder, dried oregano, sea salt, and black pepper.
Dip the chicken breast into the egg white to coat completely, then dredge it in the parmesan mixture, pressing firmly so the crust adheres to both sides.
Heat the olive oil in a non-stick skillet over medium heat. Add the chicken and cook for 5-6 minutes per side until the crust is golden brown and the internal temperature reaches 165°F.
While the chicken is cooking, warm the marinara sauce in a small saucepan over low heat.
Once the chicken is finished, remove it from the skillet and set aside. In the same skillet, add the zucchini noodles and sauté for 2 minutes until just tender.
Place the zucchini noodles on a plate, top with the crispy chicken, and finish by spooning the warm marinara sauce over the center.
