Heat olive oil in a large skillet over medium heat.
Add zucchini and onion. Season with half of the salt, pepper, and garlic powder.
Sauté 3 minutes until vegetables begin to soften.
Push the veggies to the edge of the pan and add the ground chicken. Season with the remaining salt, pepper, and garlic powder. Cook until no longer pink, breaking it up as it cooks.
Stir in diced tomatoes with juices.
Simmer 5-7 minutes until most of the liquid has evaporated and the veggies are cooked to your desired texture.
Serve over rice and finish with Parmesan or cheese of choice.
