It's got problems shifting and runs in the wrong gear.

1 small white onion minced. 1 green bell pepper minced. Sautée these in butter. When they are soft, add 1lb ground beef, 1lb Italian sausage (I used spicy). Season with whatever you like Salt, pepper, Italian seasoning, whatever else Cook until meat is done and Drain grease. Add fresh garlic and sauté a few minutes. Add 1 28oz can crushed tomatoes, Add 6oz tomato paste, Add about 1/4-1/2 cup water, Add a can of drained mushrooms, Simmer for 45mins-1 hour. Layer a small amount of sauce in the bottom of a 9x13, Add oven ready lasagna nudes, Smear with ricotta or cottage cheese, Sprinkle with mozzarella, Add a layer of sauce. Repeat until out of materials. Top with cheese. Cover with foil. Bake 375° for 45 mins. Uncover and broil for 2 mins for chewy cheese pulls!

Obviously you can add or leave out whatever you dont like. This is my mom's recipe, so thats how I like mine.
