Preheat the oven to 375°F. In a 9 x 13-inch casserole dish spread a layer of Meat Lovers Sauce and cover it with two Lasagna sheets. Top the Lasagna sheets with another layer of Meat Lovers Sauce, evenly distributed, then top with Alfredo sauce and finely grated Parmigiano Reggiano cheese (around 1/5 of the quantity).
Repeat the steps to form four other layers. Top the last layer with Meat Lovers Sauce, Alfredo sauce and a generous amount of grated Parmigiano Reggiano cheese. Bake until golden brown, around 20 minutes.
