In a medium bowl, combine the ground chicken, egg, almond flour, garlic powder, onion powder, dried oregano, sea salt, and black pepper.
Gently mix the ingredients by hand until just incorporated, then roll into 8 even meatballs.
Heat the olive oil in a large skillet over medium heat.
Place the meatballs in the skillet and sear for 4-5 minutes per side until they develop a golden-brown crust and are cooked through.
Pour the marinara sauce into the skillet, reduce heat to low, and simmer for 5 minutes to infuse the meatballs with flavor.
While the sauce simmers, lightly sauté the zucchini noodles in a separate pan for 2 minutes until just tender.
Divide the zucchini noodles into bowls and top with the meatballs and plenty of warm marinara sauce.
