Spray an oven safe pan with olive oil spray and cook turkey sausage through. Add garlic to pan and saute for a minute, then add a zucchini and spinach. Spray with additional olive oil spray and cook until zucchini is crisp tender. Add in basil and stir. Remove from heat. Flatten veggies and meat down a bit with your spatula, and then cover mixture with tomato sauce. Mix one egg, and T of Parmesan cheese into ricotta and sprinkle with fresh ground pepper. Layer ricotta mixture on top sauce. Finally, top with mozzarella cheese. Place in your broiler on low for 5-10 minutes or until cheese gets nice and toasty brown. Keep an eye on it, as it happens fast! Remove from oven and let sit for a few minutes. Just before serving, make a small cut into the lasagna and very carefully drain out the excess water from the pan. While this step is optional, because zucchini releases so much water, I think it's worth it! Just use those oven mitts and be careful!! Top with extra Parmesan cheese and sauce, if desired. Enjoy!
