I mix egg noodles, cottage cheese, sour cream, and green onions. Sometimes I make a casserole with it and layer it with tomato sauce with ground beef in it, and top it with cheddar cheese. My kids love it. My husband doesn't.
Growing up, my mom used to make a casserole of egg noodles, cut up ham, sour cream and a little onion. It was really good. It is a recipe my dad's mom brought over with her from Europe. She was Polish and grew up in Austria.
