Spinach and Zucchini Lasagna

"This Spinach and Zucchini Lasagna is vegetarian, low carb and gluten-free. It is made with tomato sauce, skinny ricotta, mozzarella and zucchini noodles.Instead of lasagna noodles I used zucchini noodles. I sliced the zucchini very thin using my Stainless Steel Mandoline Slicer. It is a very cool and useful kitchen gadget. I got this last Christmas from my mother-in-law and I love it because it makes exceptionally even slices. It easy to clean but of course you have to be very careful since the blades are very sharp. I love to wear my cut resistant gloves when I am using my mandoline because it gives me more protection."
