Preheat oven to 350 degrees F. Line a baking sheet with Parchment paper, then spray with cooking spray. Set aside.
Wash zucchini under cold water. Cut the zucchini in half-length wise, then in half, resulting in 4 zucchini boats. Using a spoon, scoop the seeds out, making sure not to remove too much of the vegetable.
Cover the bottom of each zucchini piece with sauce, then layer with spinach. Sprinkle cheese over the spinach. Top tow of the boats with green peppers, and two with cherry tomatoes, then sprinkle with parsley
Place in the oven or toaster oven at 350 degrees for ~15 minutes or until the cheese is golden brown. Add pepper or other spices, to taste
