Recently, vegan singer Leona Lewis called upon veg-friendly chef Aldo Zilli to cater four of her upcoming UK tour dates. Due to Lewis’ ethics, no meat is allowed on tour, which is no problem for newly plant-based Zilli, owner of award-winning vegetarian eatery Zilli Green. The high-profile UK chef says that he prepares spelt, barley, and quinoa dishes for Lewis so that the songstress can maintain energy on stage. Zilli has previously worked with notable musicians including Freddie Mercury, George Michael, and legendary musician and longtime vegetarian Sir Paul McCartney. Earlier this year, UK newspaper The Independent named Zilli Green London’s Best Restaurant in its 2010 Green Awards.
