Hally I think I could feed 12 with this recipe , it makes a LOT , I have made three lasagnes one large two smaller,  I had to make another batch of bechmale sauce  just 1/3 of the recipe , I gave the dried mushrooms a blitz , which was a good idea, only soaked them for about an hour, didn't have extra mushrooms or capsicum so put on 400 gms thinly sliced zucchini , the mixture tastes so good.   Thanks for bumping this, I will be making it again.
