Slice the chicken breast into two thin cutlets and season both sides with sea salt and black pepper.
In a shallow bowl, whisk the egg white until it becomes slightly frothy.
In a separate shallow bowl, combine the almond flour, parmesan cheese, garlic powder, and dried oregano.
Dip each chicken cutlet into the egg white, then press firmly into the parmesan mixture to ensure an even coating on both sides.
Heat the olive oil in a non-stick skillet over medium heat.
Add the chicken to the skillet and cook for 4-5 minutes per side until the crust is golden brown and the chicken is cooked through.
While the chicken is cooking, lightly sauté the zucchini noodles in a separate pan for 2-3 minutes until just tender.
Warm the marinara sauce in a small saucepan over low heat until simmering.
Plate the zucchini noodles, place the crispy chicken on top, and finish with a generous pour of the zesty marinara sauce.
