Place the chicken breast between two sheets of parchment paper and pound to an even half-inch thickness.
In a shallow bowl, whisk the egg white until slightly frothy.
In a separate shallow dish, combine the almond flour, parmesan cheese, dried oregano, sea salt, and black pepper.
Dip the chicken into the egg white, then dredge in the parmesan mixture, pressing firmly to ensure a thick, even coating.
Heat the olive oil in a non-stick skillet over medium heat and sear the chicken for 5-6 minutes per side until golden brown and cooked through.
While the chicken rests, add the zucchini noodles to the same skillet and sauté for 2 minutes until just tender.
Warm the marinara sauce in a small saucepan over low heat.
Plate the zucchini noodles, top with the crispy chicken, pour over the marinara sauce, and garnish with fresh basil.
