A little more than a month after organizing a push for more diverse vegetarian and vegan options in Capitol Hill cafeterias, the Vegetarian Caucus will host a luncheon April 22 to inform congressional staffers about the “benefits of a plant-based lifestyle.”

More than 200 Hill staffers have signed up for the event, according to the Physicians Committee for Responsible Medicine, which is co-hosting the luncheon. The meal will feature a flavorful menu of kale chips, cucumber gazpacho, grape leaves with tzatziki sauce and reverse osmosis water.

Staff in attendance will hear from Elizabeth Kucinich, director of the PCRM and wife of former Rep. Dennis Kucinich of Ohio. Both Kuciniches live vegan lifestyles, and pushed for better vegetarian and vegan options in Capitol Hill cafeterias during Kucinich’s time in Congress.

“Capitol Hill’s growing interest in the benefits of a vegetarian lifestyle is evident in the overwhelming enthusiasm for this Earth Day event,” said Elizabeth Kucinich, who will offer an introduction at the luncheon. “Within hours of sending the Veggie Caucus invitation, we received hundreds of RSVPs from congressional staffers.”

Other speakers at the luncheon include John Pierre, a celebrity personal trainer to stars such as Ellen DeGeneres, and Susan Levin, PCRM’s director of nutrition education.

Aside from lunch, attendees will receive a “vegetarian starter kit” and resources about vegetarian nutrition from the PCRM.

The luncheon begins at noon in Room 201 of the Capitol Visitor Center.
