Preheat your oven to 400°F and line a baking sheet with parchment paper.
In a large mixing bowl, combine the ground chicken, egg, almond flour, garlic powder, onion powder, dried oregano, sea salt, and black pepper.
Gently mix the ingredients until just combined, then form the mixture into 1-inch meatballs.
Place the meatballs on the prepared baking sheet and lightly drizzle with olive oil.
Bake for 15-18 minutes, or until the meatballs are cooked through and have a golden exterior.
While the meatballs bake, warm the marinara sauce in a large skillet over medium-low heat.
Once the meatballs are done, transfer them to the skillet and toss gently to coat them in the warm sauce.
In a separate pan, flash-sauté the zucchini noodles for 2 minutes until they are just tender but still have a slight crunch.
Divide the zucchini noodles into bowls, top with the meatballs and sauce, and finish with a sprinkle of parmesan cheese.
