Pesto Lasagne

Preheat the oven to 350 degrees F. Butter a 13 by 9 by 4 baking dish and add a thin layer of besciamella (bechamel sauce). Cover with a layer of lasagna noodles, and then another thin layer of besciamella. Gently spread about 4 tablespoons pesto across the surface, and then top with about 2 tablespoons Parmesan. Repeat until you finish layering the lasagne. Top with a final layer of noodles and spread a final very thin layer besciamella, pesto, Parmesan cheese and a little butter to help the cheese crisp-up when cooked in the oven. Cook the lasagne for about 30 minutes. Serve dressed with some Parmesan and a drop of extra-virgin olive oil.
