THIS WAS SO AWESOME!!! I used whole wheat lasagna noodles, and you can't even tell the difference. I also skipped the parsley. My husband is a big meat eater, so he's never thrilled when we have a meatless night. After having this, however, he said it was the best lasagna he's ever had and prefers it over meat lasagnas even. WOW! great leftover too. not very kid friendly though, with the mushrooms and onions.
