It looks really good in the picture, doesn't it? It looks really good when you make it too! "Lasagna" does not describe this dish, and it is disappointing because of the name. I used the full 15 oz. container of ricotta and 1/2 a cup of parmesan. You need it. Yes - definitely season the veggies! Salt, pepper, oregano, basil. If you want to call this lasagna, you need to add pasta. Otherwise, it needs a new name for sure. Although it was good for a vegetarian dish, it was a disappointment for the "regular" members of my family. This is a not a main dish for "regular" people without adding pasta at least.
