In a medium bowl, combine the ground chicken, egg white, parmesan cheese, sea salt, black pepper, dried oregano, and garlic powder.
Gently mix the ingredients until just combined and form into 1-inch meatballs.
Heat the olive oil in a large non-stick skillet over medium heat.
Add the meatballs to the skillet and sear until golden brown on all sides, about 5-6 minutes.
Add the diced onion and minced garlic to the skillet, sautéing for 2 minutes until fragrant.
Pour in the tomato puree and stir to coat the meatballs, then reduce heat to low and simmer for 5 minutes until the chicken is cooked through.
Add the zucchini noodles to the skillet and toss gently for 1-2 minutes until they are slightly softened but still have a bite.
Garnish with freshly chopped basil and serve immediately.
