I love this recipe. Again, it's a way to sneak a variety of veggies into my son's diet. I really don't even miss the meat when I make it. I'm sure it would even be good if you tossed some ground turkey or beef into the mix.
Simmer tomatoes with juice, tomato sauce, oregano, basil and black pepper in medium saucepan over low heat.
Meanwhile, cook and stir onion and garlic in hot oil in large skillet over medium-high heat until onion is golden. Add zucchini, mushrooms, carrot and green pepper. Cook and stir until vegetables are tender, 5-10 minutes.
Stir vegetables into tomato mixture; simmer 15 minutes.
Combine mozzarella, cottage and Parmesan cheeses in large bowl, blend well.
Spoon about 1 cup sauce in the bottom of 12x8" glass baking dish. Place a layer of noodles over sauce, then 1/2 of the cheese mixture and 1/2 of the remaining sauce. Repeat layers of noodles, cheese mix and sauce.
Bake in preheated 350 degree oven 30-45 minutes or until bubbly. Let stand 10 minutes. Garnish with parsley, if desired.
