I have been on the hunt for some time for a great vegetable lasagna recipe. I have yet to find one that I love. If you are familiar with Stouffer vegetable lasagna I want something similar to that in construction but homemade and with better flavor. I fondly like to think I can do better than a cheap frozen lasagna.

Mainly, I like the idea of a white sauce and crunchy topping.
I do not mind complicated recipes and I love all kinds of vegetables. As for cheese, the only kind of cheese I really dislike is smoked ricotta.
So, do any of you have any tried and true recipes for me to try out?
Thanks in advance!
