In a small bowl, combine the salt, tomato paste, onion powder, garlic powder, dried chives, dried parsley, thyme, dill, and Peperoncino. Mix well and spread over the roast. Pour the beef broth around the roast. Cover the slow cooker and cook on high for 4 hours or low for 8 hours.
Carefully remove the roast from the slow cooker and set aside. Whisk together the corn starch and water until smooth. Add the mixture to the liquid left in the slow cooker and stir well. Let the mixture cook on high for about 10 minutes or until thickened.
Slice the beef and serve the sauce over top. Enjoy!
