When does Jamie Oliver's Food Revolution return?

Jamie Oliver's Food Revolution (retitled Jamie's American Food Revolution in the United Kingdom) is a television show on ABC from March 2010 until summer 2011. The show was produced by British chef Jamie Oliver and Ryan Seacrest, following Oliver as he attempted to reform the US school lunch programs, help American society fight obesity, and change their eating habits. After two episodes, the show was cancelled because of poor ratings and replaced by repeats of Dancing with the Stars.
The show premiered on ABC on March 21, 2010, in the UK on Channel 4 on September 13, 2010. In the second season, Oliver took his food revolution to Los Angeles, California, home to the 2nd largest public school district in the US. Much of the season revolved around the Los Angeles Unified School District board of education's refusals to allow him to film in schools.
