Agreeing with the others present, I also offer Marooned or Annic Nova as interesting starter adventures. The Imperial Fringe is another good one. Some Kieth Bros. folio adventures are good too. Lots of JTAS Casual Encounters or entries from 76 or 101 Patrons can be good starters. So too can 'we have a ship... off we go exploring/trading/blowing *@#! up'. And another good option are some of the Mercenary Tickets from Book 4 or JTAS. (Ticket to Swords IIRC might be interesting...).
