Top Review by Linorama

Delicious! I made this for a romantic meal with DH and it was incredible. I served it with a tomato-fennel soup as a starter. We would be hard pressed to go out for a vegetarian meal and get an entree this wonderful AND pretty. I used soy parmesan and En-Er-G egg substitute and it worked beautifully. Update: I made these for the family and not only did everyone love them, but the leftovers reheated perfectly in the microwave. Thank you for a fabulous recipe!
