Lasagna

Preheat oven to 350ºF.

Brown the sausage, and add the Ragu sauce.

Melt butter, the whisk in the flour. It will become a ball. Whisk in milk, stirring constantly, until it comes to a boil. It can burn easily at this stage. Boil and stir for 1 minute. Take off of heat, and stir in one cup of cheese.

In a 13×9 pan, spread a thin layer of Ragu (to prevent sticking). Lay down three noodles, then a third of the white sauce, a third of the red sauce and one cup of cheese. Repeat two more times.

Bake uncovered 30 minutes, then cover and bake for 15 minutes.

Let sit for 15 minutes, then serve.
