Preheat oven to 350F.

Brown ground beef in a large skillet over medium-high heat, breaking it up as it cooks. Drain grease if necessary and return to pan; add the tomato sauce, salt and pepper to skillet. Stir mixture and reduce heat to low. Let simmer for about 5-10 minutes.

Meanwhile, boil egg noodles in a large pot of water until al dente. Drain water. Set noodles aside.

In a mixing bowl, stir together sour cream and cottage cheese. Gentle stir in cooked egg noodles. Sprinkle with a little black pepper and gently stir until noodles are coated. Stir in green onions.

Grease a 9×13-inch baking pan with non-stick spray. Layer half the noodles in the bottom of the pan, spread out evenly. Spread half of the meat mixture over the noodles, sprinkle with half the cheese. Repeat layers again, with remaining noodles, the rest of the meat mixture and then ending with the cheese.

Bake for 20 minutes or until cheese is melted and bubbly.
