Cut chuck roast into large chunks and place in the bowl of the Instant Pot.
Season with salt, garlic powder, onion powder, pepper, parsley, and Italian seasoning.
Pour beef broth around the meat.
Top meat with banana peppers.
Place lid on Instant Pot and set to pressure cook for 35 minutes. Allow the pot to naturally release for 10 minutes, then finish with a quick release to remove remaining pressure.
After the pin on the top has dropped, remove lid and take the meat out of the pot.
Shred the meat with a fork and then return the meat to the pot and stir to combine it with the juices.
Serve on a hard roll topped with provolone cheese and additional banana peppers (optional).
