Add all of the ingredients to the pot and put the lid on.
Set on high pressure for 40 minutes. When the time is up leave under pressure for another 20 minutes
Release the pressure if necessary and then remove the lid. Now remove the beef to a bowl and shred using 3 forks (reserve the gravy for dipping).
Add the meat to French bread with melted cheese (or a hoagie sub in the US) and add your desired garnish (usually sliced tomatoes, shredded lettuce and pickles). Serve and enjoy.
