Begin by placing the beef chuck roast in the crock pot or slow cooker.
Add the beef broth, sliced pepperoncini peppers, onion, minced garlic, dried oregano, dried basil, dried thyme, salt, and black pepper to the crock pot.
Cover the crock pot and cook on low heat for 8-10 hours or on high heat for 4-6 hours, or until the beef is tender and easily shreds apart.
Once the beef is cooked, remove it from the crock pot and shred it using two forks.
Return the shredded beef to the crock pot and mix it with the cooking juices to ensure it absorbs all the flavors.
Slice the sandwich rolls and lightly toast them if desired.
Assemble the sandwiches by placing a generous amount of the shredded beef on the bottom half of each roll.
If desired, top the beef with a slice of provolone cheese.
Add extra pepperoncini peppers and fresh basil leaves for an extra kick of flavor and freshness.
Serve the sandwiches hot, and pair them with a side of au jus or Italian dipping sauce for an authentic experience.
