1. Preheat oven to 375. Bring a pot of water to a boil and cook the pasta one minute less than the directions call for. Drain very well and add to a 9x12 baking dish.
2. Stir in cottage cheese, cheddar cheese, sour cream, milk, Parmesan cheese, salt and pepper. In a small bowl, stir the bread crumbs and melted butter together. Sprinkle evenly over the top and bake for 35 minutes, or until top is golden brown and bubbling.
