My first lasagne was from Julia Child, Lasagne à la française (From Julia's Kitchen), and I have used variations of it ever since. I make béchamel and tomato sauces and sautée eggplant, mushrooms and spinach for the layers. I generally forgo the ricotta--I don't think it adds much more than calories. No meat, you notice, but it is a big hit whenever I serve it. As for the pasta, I either make it or use commercial dried, 2 or 3 sheet in boiling water for a few minutes, then onto towels.
