This is another version of macaroni and cheese. I haven't tried it yet, I'm putting it here so I'll be able to find it quickly when I'm ready to make it.

2 cups egg noodles (or macaroni or small shells)
1 cup cottage cheese or ricotta cheese
1/2 cup sour cream (can be low fat or fat free)
3 tablespoons grated Parmesan cheese
1 egg
2 cups shredded Cheddar cheese
1 teaspoon Worcestershire sauce
1/4 cup milk
1/4 teaspoon salt
1/4 teaspoon ground black pepper
3 tablespoons butter

1. Cook noodles al dente. Drain. Set aside.
2. In a large mixing bowl, mix together cottage cheese, sour cream, parmesan, 1 egg, 1 cup cheddar cheese, Worcestershire sauce, milk, butter or margarine, and salt and pepper. Stir in cooked noodles. Spread into a 9 inch square baking dish, top with remaining shredded cheese. (Cover with foil if desired.)
3. Bake at 300 degrees F (150 degrees C) for one hour, or until set.
