Preheat your oven to 400°F (200°C) and lightly grease a baking sheet with the extra virgin olive oil.
Pat the chicken breast dry with a paper towel and season both sides with sea salt and black pepper.
In a small bowl, brush the chicken breast with a thin, even layer of Dijon mustard to act as a binder.
In a separate shallow dish, combine the panko breadcrumbs, grated parmesan, garlic powder, and dried oregano.
Press the chicken firmly into the breadcrumb mixture until it is thoroughly and evenly coated on all sides.
Place the chicken on the prepared baking sheet and bake for 15 to 18 minutes, or until the internal temperature reaches 165°F.
Remove the chicken from the oven, spoon the marinara sauce over the top, and sprinkle with the shredded mozzarella cheese.
Switch the oven to the broil setting and return the chicken for 2 to 3 minutes until the cheese is bubbly and slightly golden.
While the chicken rests, lightly sauté the zucchini noodles in a non-stick pan for 2 minutes until just tender.
Plate the zucchini noodles and place the crispy chicken parmesan on top to serve immediately.
