Cover the surface with plastic wrap to conserve.
Preheat oven to 375-380° F.
Spread some bechamel along the bottom of a 9-by 13-inches baking dish, place 1 single layer of fresh pasta over the souce. Top with more bechamel and 1 layer of lettuce. Finish with some sliced of provola cheese and parmesan cheese.Repeat with anoter layer of pasta and continue until you finish all the ingredients, you better finish the last layer with the parmesan cheese. Sprinkle with sone butter pieces.
Bake 35-40 minutes, until cheese is goldenin places and lasagna is bubbling along the edges.
