For dinner last night, we had Alberto's tofu and mushroom ravioli, which tastes almost exactly like four-cheese ravioli. It's vegan and 100% organic (New York), and I highly recommend it. The only problem I had with it was that it was a little tough, but I think that was just due to not enough time boiling.
Over it, we used Middle Earth Organics tomato and eggplant sauce, plus some Parmesan "cheese" sprinkled on top.
All in all, very good. The cost reflected the prepackaged nature of the ravioli ($3.79 [USD] a bag!), but it was a nice Saturday night treat. I'd recommend either product, especially the ravioli.
