Showtime has put in development The Middlesteins, a half-hour comedy series based on the 2012 book by Jami Attenberg, from Nina Tassler, former chairman of Showtime sibling CBS Entertainment, and Casual showrunner Liz Tigelaar.

The Middlesteins is about a suburban couple who splits up after 30 years, partly because of the wife’s obsession with food.

Girls scribe Jason Kim will pen the TV adaptation. Tigelaar will serve as showrunner and executive produce with Tassler, Attenberg, Kim and Jonathan Levin. CBS Television Studios is producing.
