This was easy to prepare and tasted fine. I cut the recipe in half and baked in a 4-inch casserole with no problems. I didn't miss having meat in it, as I have made mushroom lasagna before, but I did miss the layers of pasta. Maybe I will use larger slices of portabellos next time. Glad I tried it though, since I am trying to cut carbs and gluten due to diabetes. Thanks for posting.
