Teresa Giudice -- Leaves Cast Members Fuming ... Before Pre-Prison Reunion Taping

Some people eat their favorite meals, some people say their goodbyes ... but Teresa Giudice prepared for prison by pissing off her castmates -- showing up over 4 hours late to their reunion taping.

Sources close to the production tell us her "Real Housewives of New Jersey" co-stars were furious about the tardiness Sunday afternoon ... same for Bravo head honcho Andy Cohen.

And what's worse ... we're told Giudice continued to delay the process once they began filming -- making producers continually start and stop the taping because Teresa said she was "going through a lot" and needed a break.

Her list of visitors in prison will be short.
