Sour Cream Noodle Bake

1.25 lbs ground beef
15 oz can tomato sauce
½ tsp salt
½ tsp pepper
8 oz egg noodles (half a pound)
½ cup sour cream
1.25 cups cottage cheese
¼ to 1/2 cup sliced green onions (depending upon how onion-y you like your food)
1 cup shredded cheddar

Bring a large pot of salted water to a boil.  Cook egg noodles according to package directions.  Meanwhile, brown beef in a large skillet; drain fat.  Add tomato sauce, salt and pepper.  Stir, and let simmer while you assemble the rest of the casserole.  In a large bowl, combine sour cream, cottage cheese, and some freshly ground black pepper.  Mix in the noodles and onions.  To assemble, place half of the noodles in a 2.5 qt baking dish.  Top with half the meat mixture, then half the cheddar.  Repeat with noodles, meat and cheese.  Bake for 20 minutes @ 350 until cheese is melted.
