Melt margarine in a saucepan.

Whisk in flour until smooth.

Gradually add milk and cream, whisking constantly to avoid lumps.

Stir over moderate heat until the sauce bubbles and thickens, ensuring it remains smooth.

Season with salt, pepper, and nutmeg.

Cook lasagne noodles in boiling salted water according to package directions.

Drain the noodles and rinse with cold water to stop cooking.

Lay the noodles on a damp towel to prevent sticking.

In a large baking pan (9x13 inches), spread a thin layer of Meat Sauce Bolognese.

Top with a layer of cream sauce.

Sprinkle with grated Parmesan cheese.

Arrange a layer of cooked lasagne noodles over the sauce.

Repeat layers of meat sauce, cream sauce, cheese, and noodles until all ingredients are used, ending with a layer of cheese on top.

Bake in a preheated oven at 375°F (190°C) for 35 to 40 minutes, or until the lasagne is bubbly and the top is browned.

Let the lasagne cool for 10 minutes before cutting and serving.

Serve and enjoy. Cottage cheese or Mozzarella cheese may also be used as a topping.
