Preheat oven to 375 degrees F.
In a large bowl, add stuffing mix with half of the spaghetti sauce, garlic, ½ teaspoon oregano, parsley and pepper; mix well. Add meat and mix to incorporate all ingredients (I usually use my hand to make sure everything is incorporated).
Place meat in a 9x13 baking dish.
Add zucchini, remaining spaghetti sauce, ½ teaspoon oregano to a bowl and mix to combine. Spoon over meat mixture and cover with foil.
Bake for 25-30 minutes. Remove foil and top with cheese. Bake for another 10 minutes uncovered. Meatloaf should be 160 degrees F with cheese bubbly and melted.
Serve immediately and enjoy!
