Place the chicken breast between two sheets of parchment paper and pound to an even thickness.
In a shallow bowl, combine the almond flour, parmesan cheese, garlic powder, oregano, sea salt, and black pepper.
Press each side of the chicken breast into the parmesan mixture until it is thoroughly and evenly coated.
Heat the olive oil in a large skillet over medium heat and sear the chicken for 5-6 minutes per side until the crust is golden brown.
While the chicken cooks, spiralize the zucchini into thin noodles and warm the marinara sauce in a small saucepan over low heat.
Remove the chicken from the skillet and set aside to rest, then briefly sauté the zucchini noodles in the same pan for 2 minutes until just tender.
Plate the zucchini noodles first, top with the warm marinara sauce, and finish with the crispy parmesan chicken.
