Ingredients:

  • 2 pounds of medium to rare roast beef, cut into ½-inch-thick strips
  • Dash of salt
  • Dash of black pepper
  • 4 ounces unslated butter, divided
  • 3 tablespoons of all-purpose flour
  • 2 cups no-salt-added beef broth
  • 1 heaping teaspoon Dijon mustard
  • 12 ounces fresh button mushrooms, cleaned and sliced

  • ¼ red wine
  • 1 large shallot, chopped
  • 6 garlic cloves

  • Cooked noodles

Cover and simmer for 50 to 60 minutes, or until meat is tender.

Five minutes before serving, stir in the sour cream and red wine. Add salt and pepper to taste, serve over cooked noodles.
