In a large skillet, heat the olive oil over medium heat.

Add the diced onion and minced garlic, and sauté for 2-3 minutes until softened.

Increase the heat to medium-high and add the ground beef. Cook until browned, about 5-7 minutes.

Stir in the sliced zucchini, salt, pepper, and Italian seasoning. Cook for another 5 minutes, stirring occasionally.

Pour in the chicken broth and soy sauce, and bring the mixture to a gentle simmer.

Let it cook for an additional 5 minutes, or until the zucchini is tender and the liquid has reduced slightly.

Remove from heat and garnish with chopped parsley before serving.
