Place the chicken breast between two sheets of parchment paper and pound to an even half-inch thickness.
In a shallow bowl, combine the almond flour, grated parmesan, garlic powder, dried oregano, sea salt, and black pepper.
Press the chicken breast firmly into the parmesan mixture on both sides until thoroughly coated.
Heat one teaspoon of olive oil in a non-stick skillet over medium-high heat and sear the chicken for 5-6 minutes per side until the crust is golden brown and the chicken is cooked through.
Remove the chicken from the pan and set aside to rest.
In the same skillet, add the remaining teaspoon of olive oil and the zucchini noodles, sautéing for 2 minutes until just tender.
In a small saucepan, warm the marinara sauce over low heat until simmering.
Plate the zucchini noodles, top with the warm marinara sauce, and place the crispy chicken on top to serve.
