As the new executive chef at Ojai's most storied restaurant, J. Richard Sejkousky is bringing vegetarianism back to the menu, one dish at a time. "More and more, it's the way I'm eating. I think a lot of other people are interested in eating that way, too," said Sejkousky, a former high school English teacher turned chef who joined the Ranch House in September after stints at the Mupu Grill in Santa Paula, Sheila's Wine Bar in Camarillo and Cafe Firenze in Moorpark.
