In an 8" x 8" baking dish, spred a thin layer of alfredo sauce on the bottom.
Layer the zucchini on top of the alfredo sauce then spoon on a layer of ricotta cheese then sprinkle a layer of mozzarella cheese. Sprinkle a pinch of salt, pepper and Italian spices (optional). Top with a layer of noodles.
Repeat the layering process with the squash, spinach and carrots topping each layer with alfredo sauce, ricotta cheese, a sprinkle of mozzarella and then noodles.
After the carrots layer, place a final layer of alfredo sauce on the noodles then top with remaining mozzarella and cheddar cheese. Be sure to cover the noodles so they don't dry out.
Bake at 350˚ for 35-40 minutes or until the center is hot.
