For sauce, in a medium saucepan, cook zucchini, onion, and garlic with a little bit of olive oil. Add tomatoes, sauce, paste and seasonings. Cook, covered, for 15 minutes. Meanwhile cook noodles for 10-12 minutes. Drain, rinse with cold water, drain well.
For filling, combine egg with ricotta and parsley.
Layer half the cooked noodles in a 9x13 pan. Spread with half the filling. Top with half the sauce and half the mozzarella. Repeat layers. If desired, sprinkle with additional grated Parmesan. Bake at 375 for 30-35 minutes or till heated through. Let stand 10 minutes before serving.

SUBSTITUTIONS: I don't always have mozzarella on hand, so I cover it with shredded colby jack and Alan never seems to mind.
