Cook the tagliatelle very al dente. Heat the meat of your choice or tomato sauce. Cut the Mozzarella into thin slices (if it is too wet, pat it with clean napkins and dry it well).
Mix tagliatelle with 1/3 of the tomato sauce. Butter a shallow baking pan. Arrange the tagliatelle in thin layers into the baking pan. Top each layer with the sauce, cover with Mozzarella slices and sprinkle with Parmigiano.
The top layer should be Mozzarella lightly covered with the remainder of the sauce. Dot with butter and bake for 20 mins. at about 350ºF.
Melted Mozzarella should be lightly brown on top. Remove from oven, let rest for 10 mins. and serve.
Note:
Tagliatelle may be replaced with dry pasta (e.g., penne or ziti).
