Jeremie Banet, a fund manager at Pacific Investment Management Co. specializing in inflation-protected bonds, plans to leave the firm on June 10 to start a food truck in Los Angeles and Orange County.

Banet, 36, is leaving the Newport Beach, California-based company on good terms after a “change of heart,” he said today in a telephone interview. Banet, who joined Pimco in 2011, said he will sell croque monsieur, grilled ham-and-cheese sandwiches that originated in French cafes.

Banet, who’s French, joined Pimco in mid-2011 after a career trading inflation-linked investments at Nomura Securities Co. and BNP Paribas SA. Mark Porterfield, a Pimco spokesman, and Mihir Worah, one of Pimco’s six deputy chief investment officers, didn’t immediately respond to messages seeking comment.

Pimco, led by Bill Gross, put in place the six deputy CIOs earlier this year after former Chief Executive Officer Mohamed El-Erian’s resignation triggered the biggest management shakeup in its history.

Banet said his family has a history in the food business. His grandmother owned and edited culinary magazine Cuisine et Vins de France in the 1950s and 1960s, he said.
