• Step 1: Place the beef chuck roast in a slow cooker. Sprinkle with the Italian seasoning, garlic powder, onion powder, salt, and black pepper. Pour in the beef broth.
• Step 2: Cook on low for 7-8 hours or on high for 4-5 hours, until the beef is very tender and easily shreds with a fork.
• Step 3: Remove the beef from the slow cooker and shred it using two forks. Return the shredded beef to the cooking liquid.
• Step 4: Toast the Italian rolls until golden brown. Divide the shredded beef evenly among the rolls, spooning some of the cooking liquid over the top.
• Step 5: Top with giardiniera and/or Provolone cheese, if desired. Serve the sandwiches with the remaining cooking liquid for dipping.
