Brown ground chuck in a large skillet. Drain fat, then add tomato sauce. 1/2 teaspoon salt and plenty of freshly ground black pepper. Stir, then simmer while you prepare the other ingredients.

Cook egg noodles until al dente. Drain and set aside.

In a medium bowl, combine sour cream and cottage cheese. Add plenty of freshly ground black pepper. Add to noodles and stir. Add green onions and stir.

To assemble, add half of the noodles to a baking dish. Top with half the meat mixture, then sprinkle on half the grated cheddar. Repeat with noodles, meat, then a final layer of cheese. Bake for 20 minutes, or until all cheese is melted.
