Preheat the oven to 400 degrees and spray a 9 by 13 baking dish with cooking spray. Set aside.
Place shredded zucchini in a strainer and sprinkle with salt. Allow the zucchini to sit for 10 minutes.
Press out all extra moisture, the more the better.
Combine zucchini, eggs, basil, oregano, garlic powder, pepper, Parmesan cheese, and 1 ½ cups of shredded cheese. Mix well. Press into the prepared 9 x 13 pan. Bake for 20 minutes.
Meanwhile, heat 1- 1 ½ teaspoons of olive oil over medium heat. Add onion and minced garlic. Cook for 3 minutes.
Add ground sausage. Cook until no longer pink. Drain if necessary.
Stir in tomato sauce.
Spread meat mixture over the zucchini crust.
Cover with remaining cheese and sprinkle diced green pepper on top. Feel free to sprinkle a little more oregano, basil, or even some parsley on top.
Increase the oven temperature to 450 degrees and bake for an additional 20 minutes, until cheese is melted.
