She (Michelle Merage Janavs) was NOT the inventor of Hot Pockets. I worked for the company in the 80s and 90s before it was sold to Nestle. Hot Pockets were developed by Paul and David Merage.

Janavs’ family fortune comes from Chef America Inc., which was founded by her father, Paul Merage, and his brother David, who developed the Hot Pocket line of frozen calzone-style snacks. Chef America was sold to Nestle in 2002 for $2.6 billion. The Merage family name also is attached to the Merage Jewish Community Center in Irvine and the business school at UC Irvine.
