I bought zucchini, yellow squash, bell peppers, onions, carrots and mushrooms from the farmer's market and ethan made the noodles from scratch with our pasta maker!
I steamed the veggies and made a sauce with canned tomatoes, tomato sauce and paste, garlic and fresh basil. The cheese was a mixture of cottage cheese, cream cheese and an egg - a low fat version of ricotta, if you will. I also layered in some mozzarella cheese as well.
I layered sauce, noodles, veggies and cheese in two tiers and topped with more sauce and cheese. It was really fantastic and cheesy, and we really didn't miss the full fat ricotta as much as I had worried. A great light & healthy, yet comforting dish!
