Preheat the oven to 350°F.
Brown the ground chuck in a large skillet. Drain the fat, then add the tomato sauce, 1/2 teaspoon salt, and plenty of freshly ground black pepper. Stir, then simmer while you prepare the other ingredients.
Cook the 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 the noodles and stir. Add the green onion and stir.
To assemble, add half of the noodles to a baking dish. Top with half of the meat mixture, then sprinkle on half of the grated cheddar. Repeat with the noodles, meat, then a final layer of cheese. Bake for 20 minutes, or until all the cheese is melted. Serve with crusty French bread.
