An elegant way to elevate leftover Pot Roast or Brisket. Shred the meat and mix with cheese, egg, parsley and garlic, then gently fill pasta shells and top with sauce.
Preheat oven to 375°F. Prepare pasta shells according to package directions; drain. Set aside. Shred beef Pot Roast with two forks.
Meanwhile, combine pot roast, cottage cheese, 1/2 cup Parmesan cheese, egg, parsley and garlic in large bowl.
Fill shells evenly with beef mixture. Spread 1 cup pasta sauce on bottom of 11 X 7-inch glass baking dish. Arrange shells in dish; top with remaining sauce.
Cover with aluminum foil. Bake in 375°F oven 20 minutes. Remove foil; sprinkle with remaining 1/4 cup cheese. Bake, uncovered, 5 to 8 minutes or until cheese is slightly browned and sauce is bubbly. Season with salt and pepper, if desired. Garnish with basil, if desired.
