Sausage and mushroom lasagne

Right, I thought of this a while back, and thought I'd better write it down before I forgot. On the bottom layer, a mix of sausage meat and tomatoes. On the top layer, lots of mushrooms with thyme and oregano. Plus the white sauce in between, and lots of parmesan on the top. The good thing about this is that sausage meat is usually very well seasoned, so you can make a really nice meat sauce quite quickly.

The picture is of the second helping, hence the mess.
